1. INTRODUCTION

In this age of modernization where the world is experiencing a fast and robotic life,

one needs to be as fast and robotic as the present world. My intention by this project is to

actually interface a mobile phone with that of a personal computer. Here, by using a GSM

Modem we are actually making a personal computer to work like a mobile phone.

1.1. OBJECTIVE AND SCOPE OF THE SYSTEM

Computers have become an unavoidable part of our life. There are a lot of things

which we can do using our systems. Computer systems can perform a large variety of

operations. But it works only based on the instructions given by the user.so our physical

presence is needed to do any operation using computers

So far there is no facility to control and monitor the system by mobile. There is

only facility of system to system controlling using LAN or internet. This system have some

limitations, such as range, in network etc.To overcome this limitation, we are developing this

new software. The Main intent of this software is to control a systems processes by sending

sms using mobile phone.We can access and control our PC like shutting down, sending mails,

file operations, starting or stopping services etc. from anywhere using a mobile phone with

lesser cost. For the working of this software application, we need a GSM modem connected

to a system and a mobile phone to send message. GSM (Global System for Mobile

communication) act as an interface for communication between computer and mobile phone

This project implements the emerging applications of the GSMtechnology. Using

GSM networks, a control system has been proposed that will act as an embedded system

which can monitor and control appliances and other devices locally using built-in input and

output peripherals.Remotely the system allows the user to effectively monitor and control the

house/office appliances and equipments via the mobile phone set by sending commands in

the form of SMS messages and receiving the appliances status. The main concept behind the

project is receiving the sent SMS and processing it further as required to perform several

operations.The type of the operation to be performed depends on the nature of the SMS sent .

By sending SMS to the modem connected to the system. The modem take the input

from mobile, that means SMS and act as what we mentioned in the SMS.A new user can

create account with the system so that he can further access the system from a remote area.

If we are sending a message-mail (along with user id, content etc.) to the GSM Modem

connected personal computer, a mail will be send to the intended recipient from our system.

By using this technique, we can even shut down our personal computer by just sending SMS.

If we need to stop a process, by sending the message- kill followed by the process name, to

the GSM Modem connected to the personal computer, we will able to kill that particular

process.

We can access and control our PC like shutting down, sending mails, file

operations, starting or stopping services etc. from anywhere using a mobile phone with lessercost. We can run any applications that you want on your home computer while you're away

from home. The best example is doing the office work from our home. We can achieve this

by using mobile phone through external GSM modem or phone which supports GSM

modem.

GSM (Global System for Mobile communication) act as an interface for

communication between computer and mobile phone. A GSM modem is a wireless modem that

works with a GSM wireless network. There are so many networks available like internet,HSPDA (High Speed Data Packet Access), Bluetooth, GPRS (General Packet Radio Service),

Wi-Fi (Wireless fidelity), etc. Here we are using the GSM network for controlling the system.

The GSM network is much cheaper than the other networks as it is readily available in the

market.GSM (Global System for Mobile Communications): It is a cellular

communicationstandard.SMS (Short Message Service): It is a service available on most

digital mobile phones that permit the sending of short messages (also known as text

messaging service).

For this application no internet connection is required. We Just require a SMS service

enabled phone The GSM network is much cheaper than the other networks. No physical

presence is needed to control a system.This systemwill be a powerful and flexible tool that will

offer this service at any time, and fromanywhere with the constraints of the technologies

being applied.

2.2 EXISTING SYSTEM

Computers have become an unavoidable part of our life. There are a lot of things

which we can do using our systems. Computer systems can perform a large variety ofoperations. But it works only based on the instructions given by the user.so our physical

presence is needed to do any operation using computers.The new age of technology has

redefined communication. Most people nowadays haveaccess to mobile phones and thus the

world indeed has become a global village. At any given moment, any particular individual

can be contacted with the mobile phone. But the application of mobile phone can not just be

restricted to sending SMS or starting conversations. New innovations and ideas can be

generated from it that can further enhance its capabilities.So far there is no facility to control and monitor the system by mobile. There is

only facility of system to system controlling using LAN or internet. This system have some

limitations, such as range, in network etc..So we need to find some new ways of quick n

efficient access of our systems from any remote areas just by using our mobile phones. By

over this problem we introduced the proposed system The Main intent of this software is to

control a systems processes by sending sms using mobile phone.We can access and control

our PC like shutting down, sending mails, file operations, starting or stopping services etc.from anywhere using a mobile phone with lesser cost. For the working of this software

3. SYSTEM DESIGN

System design is the process of developing specifications for a candidate system

that meet the criteria established in the system analysis. Major step in system design is the

preparation of the input forms and the output reports in a form to the user. The main objective

of the system design is to the package easily by any computer operator. System design is the

creative act of invention, developing new inputs, a database, offline files, method, procedures

and out for processing business to meet an organization objective. System builds information

gathered during the system analysis.

3.1 DATAFLOW DIAGRAM

A DFD is a pictorial representation of the path which data takes From its initial

interaction with the existing system until it completes any interaction. The diagram will

describe the logical data flows dealing the movements of any physical items. The DFD also

gives the insight into the data that is used in the system i.e., who actually uses it is

temporarily stored.

Fig 3.4 User process diagram


10/52



3.2INPUT/OUTPUT DESIGN

INPUTInput is considered as the process of keying in data into the system, which will be

converted to system format. The goal of the input design is to make data entry easier, logical and

free from errors. The input design is the link that ties the system into the world of its user. People

who use this software belong to different cultures and geographies. So the input screens given in

the software should be really flexible and faster to use.

The options for input data entry are as follows.

Login

The Login option helps the administrator to login to the software by entering the correct password

as input.

Insert

The insert option helps in inserting the information into the database.

Update

The update option helps in updating the scheduling information of the data in the database.

Delete

The delete option helps in deleting the data in the database.

OUTPUTThe success or failure of software is decided by the integrity and correctness output

that is produced from the system. One of the main objectives behind this sms scheduling

system is to perform the operation mentioned in the message which is sent from a mobile

phone.

The output of this software is the execution of operations such as

Setting reminder Sending mails Scheduling downloads File operations

System control (restart, shutdown, log off)


11/52



3.3 DATABASE DESIGN

The database design involves the design of database and tables that are to develop

a system. This phase creates the design of tables that are necessary. During this phase, the

tables are created and analysed for relational database management system rules, this

involves normalization activities also.

A database is a collection of interrelated data stored with minimum redundancy to

serve users quickly and efficiently. Database files are the key source of information into the

system. It is the process designing database files, which are the key source of information to

the system. The files should be properly designed and planned for collection, accumulation,

editing and retrieving the required information.

The origination of database aims to achieve three objectives

Data integration Data integrity Data independence

The proposed system stores the information relevant for processing in sql server

database. This database contains tables where each table corresponds to one particular type of

information. Each type of information in the table is called a field or column.

A table also contains records, which is a set of fields. All records in the table has

the same set of fields with different information. There are primary key fields that uniquely

identify a record in a table.

4. SOFTWARE SPECIFICATION

4.1. MICROSOFT VISUAL STUDIO

Microsoft Visual Studio is an integrated development environment (IDE)

from Microsoft. It is used to develop console and graphical user interface applications along

with Windows Forms applications, web sites, web applications, and web services in

both native code together with managed code for all platforms supported by Microsoft

Windows, Mobile, Windows, .NET Framework, .NET Compact Framework and Microsoft

Silverlight it can also develop windows presentation foundation (WPF) application.

Visual Studio includes a code editor supporting IntelliSense as well as code

refactoring. The integrated debugger works both as a source-level debugger and a machine-

level debugger. Other built-in tools include a forms designer for

building GUI applications, web designer, class designer, and database schema designer. It

accepts plug-ins that enhance the functionality at almost every level including adding

support for source-control systems (like Subversion and Visual SourceSafe) and adding new

toolsets like editors and visual designers for domain-specific languages or toolsets for other

aspects of the software development lifecycle (like the Team Foundation Server client: Team

Explorer).

Visual Studio supports different programming languages by means of language

services, which allow the code editor and debugger to support (to varying degrees) nearly any

programming language, provided a language-specific service exists. Built-in languages

include C/C++ (via Visual C++), VB.NET (via Visual Basic .NET), C# (via Visual C#),

and F# (as of Visual Studio 2010). Support for other languages such as M, Python, and Ruby

among others is available via language services installed separately. It also

supports XML/XSLT, HTML/XHTML, JavaScript and CSS. Individual language-specific

versions of Visual Studio also exist which provide more limited language services to the user:

Microsoft Visual Basic, Visual J#, Visual C#, and Visual C++.

Microsoft provides "Express" editions of its Visual Studio 2010 components Visual

Basic, Visual C#, Visual C++, and Visual Web Developer at no cost. Visual Studio 2012,

2010, 2008 and 2005 Professional Editions, along with language-specific versions (Visual


17/52



Basic, C++, C#, J#) of Visual Studio Express 2010 are available for free to students as

downloads via Microsoft's Dream Spark program.

Visual Studio does not support any programming language, solution or tool

intrinsically, instead it allows the plugging of functionality coded as a VSPackage. Wheninstalled, the functionality is available as a Service. The IDE provides three services:

SVsSolution, which provides the ability to enumerate projects and solutions; SVsUIShell,

which provides windowing and UI functionality (including tabs, toolbars and tool windows);

and SVsShell, which deals with registration of VSPackages. In addition, the IDE is also

responsible for coordinating and enabling communication between services. All editors,

designers, project types and other tools are implemented as VSPackages. Visual Studio

uses COM to access the VSPackages. The Visual Studio SDK also includes theManagedPackage Framework (MPF), which is a set of managed wrappers around the COM-interfaces

that allow the Packages to be written in any CLI compliant language. However, MPF does

not provide all the functionality exposed by the Visual Studio COM interfaces. The services

can then be consumed for creation of other packages, which add functionality to the Visual

Studio IDE.

Support for programming languages is added by using a specific VSPackage called

a Language Service. A language service defines various interfaces which the VSPackageimplementation can implement to add support for various functionalities. Functionalities that

can be added this way include syntax coloring, statement completion; brace matching,

parameter information tooltips, member lists and error markers for background

compilation. If the interface is implemented, the functionality will be available for the

language. Language services are to be implemented on a per-language basis. The

implementations can reuse code from the parser or the compiler for the language. Language

services can be implemented either in native code or managed code. For native code, either

the native COM interfaces or the Babel Framework (part of Visual Studio SDK) can be used

For managed code, the MPF includes wrappers for writing managed language services.

Visual Studio does not include any source control support built in but it defines

two alternative ways for source control systems to integrate with the IDE.A Source Control

VSPackage can provide its own customized user interface. In contrast, a source control

plugin using the MSSCCI (Microsoft Source Code Control Interface) provides a set of

functions that are used to implement various source control functionality, with a standardVisual Studio user interface MSSCCI was first used to integrate Visual SourceSafe with


18/52



Visual Studio 6.0 but was later opened up via the Visual Studio SDK. Visual Studio .NET

2002 used MSSCCI 1.1, and Visual Studio .NET 2003 used MSSCCI 1.2. Visual Studio

2005, 2008 and 2010 use MSSCCI Version 1.3, which adds support for rename and delete

propagation as well as asynchronous opening.

Visual Studio supports running multiple instances of the environment (each with its

own set of VSPackages). The instances use different registry hives (see MSDN's definition of

the term "registry hive" in the sense used here) to store their configuration state and are

differentiated by their AppId (Application ID). The instances are launched by an AppId-

specific .exe that selects the AppId, sets the root hive and launches the IDE. VSPackages

registered for one AppId are integrated with other VSPackages for that AppId. The various

product editions of Visual Studio are created using the different AppIds. The Visual StudioExpress edition products are installed with their own AppIds, but the Standard, Professional

and Team Suite products share the same AppId. Consequently, one can install the Express

editions side-by-side with other editions, unlike the other editions which update the same

installation. The professional edition includes a superset of the VSPackages in the standard

edition and the team suite includes a superset of the VSPackages in both other editions. The

AppId system is leveraged by the Visual Studio Shell in Visual Studio 2008.

4.2. .NET

The .NET Framework is a software framework developed by Microsoft that runs

primarily on Microsoft Windows. It includes a large library and provides language

interoperability (each language can use code written in other languages) across

several programming languages. Programs written for the .NET Framework execute in a

software environment, known as the Common Language Runtime (CLR), an application

virtual machine that provides services such as security, memory management, and exceptionhandling. The class library and the CLR together constitute the .NET Framework.

The .NET Framework's Base Class Library provides user interface, data

access, databaseconnectivity, cryptography, webapplication development,numeric algorithms,

and network communications. Programmers produce software by combining their own source

code with the .NET Framework and other libraries. The .NET Framework is intended to be

used by most new applications created for the Windows platform. Microsoft also produces an

integrated development environment largely for .NET software called Visual Studio.

The .Net Framework is made up of four parts,


19/52



The Common Language Runtime

A Set of Class Libraries

A Set of Programming Languages

ASP.NET Environment

The .NET Framework was intended to make Windows application much more

reliable, while also providing an application with greater degree of security. It was intended

to simplify the development of web application and services. The framework was designed to

provide a single set of libraries that would work with multiple languages. The .NET

Framework is a common environment for running Web applications and Web libraries-like

ADO.NET, ASP.NET and Windows forms- to provide advanced standard services that can

be integrated onto a variety of computer systems. The Framework provides- rich application

environment, simplified development and easy integration between a numbers of different

languages. Currently it supports Visual Basic, C++, C# and Jscript (The Microsoft version of

Java Script).

4.3. NET FRAMEWORK

The .NET Framework (pronounced dot net) is a software framework developed by

Microsoft that runs primarily on Microsoft Windows. It includes a large library and

provides language interoperability (each language can use code written in other languages)

across several programming languages. Programs written for the .NET Framework execute in

a software environment (as contrasted to hardware environment), known as the Common

Language Runtime (CLR), an application virtual machine that provides services such as

security, memory management, and exception handling. The class library and the CLR

together constitute the .NET Framework.

The .NET Framework's Base Class Library provides user interface, data access,

database connectivity, cryptography, web application development, numeric algorithms,and network communications. Programmers produce software by combining their own source

code with the .NET Framework and other libraries. The .NET Framework is intended to be

used by most new applications created for the Windows platform. Microsoft also produces

an integrated development environment largely for .NET software called Visual Studio.

C# (C sharp):C# is a new programming language designed for building a wide

range of enterprise applications that run on the .NET Framework. An evolution of C and

C++, C# is simple, modern, type safe, and object-oriented. C# code is compiled as managedcode, which means it benefits from the services of the common language runtime. These

services include language interoperability, garbage collection, enhanced security, and

improved versioning support.

C# is introduced as Visual C# in the Visual Studio .NET suite. Support for Visual

C# includes project templates, designers, property pages, code wizards, an object model, and

other features of the development environment. The library for Visual C# programming is the

.NET Framework.

THE FOUR COMPONENTS OF .NET FRAMEWORK

Common Language Runtime

One of the design goals of .NET Framework was to unify the runtime engines so

that all developers could work with a set of runtime services. The .NET Framework s

solution is called the Common Language Runtime (CLR). The CLR provides capabilities

such as memory management, security, and robust error handling to any language that work

with the .NET Framework. The CLR enables languages to inter operate with one another.

Memory can be allocated by code written in one language and can be freed by code written in

another language. Similarly, errors can be raised in one language and processed in another

language.

. NET Class Libraries


21/52



The .NET Framework provides many classes that help developers re-use code.

The .NET Class Libraries contain code for programming topics such as threading, file I/O,

database support, XML parsing, and data structures such as stack and queues. This entire

class library is available to any programming language that supports the .NET Framework.

Because all languages now support the same runtime, they can re-use any class that works

with the .NET Framework. This means that any functionality available to one language will

also be available to any other .NET language.

. NET Programming Languages

The .NET Framework provides a set of tools that help to build code that works

with the .NET Framework. Microsoft provides a set of languages that are already .NET

compatible. C#.Net is one of those languages.

VISUAL C#.NET

C# is a simple, modern, object oriented, and type-safe programming language

derived from C and C++. It will immediately be familiar to C and C++ programmers. C#

aims to combines the high productivity of Visual Basic and a new programming languagedesigned for building enterprise application that run on the .NET Framework. C#, which is

evolution of C and C++, is type safe and object oriented. Because it is compiled as managed

code, it benefits from the services of the common language runtime, such as language

interoperability, enhanced security, and garbage collection.

Visual C# .NET is Microsoft s C# development tool. It includes an interactive

development environment, visual designers for building Windows and web applications, a

compiler, and debugger. Visual C#.Net is part of a suite of products, called Visual Studio.

NET, that also includes Visual Basic .NET, Visual C++, .NET and the Jscript script language.

All of these language provide access to Microsoft .NET Framework, which includes a

common execution engine and a rich class library. The .NET Framework defines a Common

Language Specification (CLS), a sort of ligua Franca that ensures seamless interoperability

between CLS-compliant languages and class libraries.

Visual C#.NET is currently part of the Visual Studio . NET. Microsoft Visual C#.NET is the

tool set for creating XML Web services and Microsoft .NET-connected applications for

Microsoft Windows and the web.


22/52



C#.NET

It provides the richest level of integration among presentation technologies,

component technologies and data technologies. The entire architecture has been created tomake it easy to develop for the desktop. The framework starts al the way down at the memory

management and component loading level, and goes all the way up to the multiple ways of

rendering user and program interfaces. In between there are layers that provide just about any

system level capability that a developer would need at the base is the common language

runtime. This is the heart of .net. The middle layer includes the next generation of standard

system services such as classes that manages data and xml.

The top layer includes user and program interfaces it includes- windows forms

web forms

.NET Framework Class Library

Gain mature and powerful, built-in functionality, including a rich set of collectionclasses, networking support, multithreading support, string and regular expression classes,

and broad support for XML, XML schemes, XML namespaces, XSLT, XPath and SOAP.

Some of the main features of the languages are as follows:

Object Oriented Language.

Powerful Language for making applications.

Security.

Multithreading and Multitasking.

Internet Programming.

Intranet Programming

ASP.Net 3.5


23/52



ASP.NET is a programming framework built on the common language runtime that

can be used on a server to build powerful Web applications.ASP.NET offers several

important advantages over previous Web development models.

The advantages are:

Enhanced Performance

ASP.NET is compiled common language runtime code running on the server. Unlike

its interpreted predecessors, ASP.NET can take advantage of early binding, just-in-time

compilation, native optimization, and caching services right out of the box. This amounts to

dramatically better performance before you ever write a line code.

World-Class Tool Support

The ASP.NET framework is complemented by a rich toolbox and designer in the

Visual Studio integrated development environment. WYSIWYG editing, drag-and-drop

server controls, and automatic deployment are just a few of the features this powerful tool

provides.

Power and Flexibility

Because ASP.NET is based on the common language runtime, the power and

flexibility of that entire platform is available to Web application developers. The .NET

Framework class library, Messaging, and Data Access solutions are all seamlessly accessible

from the Web. ASP.NET is also language-independent, so you can choose the language that

best applies to your application or partition your application across many languages.

Simplicity

ASP.NET makes it easy to perform common tasks, from simple form submission and

client authentication to deployment and site configuration. For example, the ASP.NET page

framework allows you to build user interfaces that cleanly separate application logic from


24/52



presentation code and to handle events in a simple, Visual Basic - like forms processing

model. Additionally, the common language runtime simplifies development, with managed

code services such as automatic reference counting and garbage collection.

Manageability

ASP.NET employs a text-based, hierarchical configuration system, which simplifies

applying settings to your server environment and Web applications. Because configuration

information is stored as plain text, new settings may be applied without the aid of local

administration tools. This "zero local administration" philosophy extends to deploying

ASP.NET Framework applications as well. An ASP.NET Framework application is deployed

to a server simply by copying the necessary files to the server. No server restart is required,

even to deploy or replace running compile code.

Scalability and Availability

ASP.NET has been designed with scalability in mind, with features specifically

tailored to improve performance in clustered and multiprocessor environments. Further,

processes are closely monitored and managed by the ASP.NET runtime, so that if one

misbehaves (leaks, deadlocks), a new process can be created in its place, which helps keep

your application constantly available to handle requests.

Customizability and Extensibility

ASP.NET delivers a well-factored architecture that allows developers to "plug-in"

their code at the appropriate level. In fact, it is possible to extend or replace any

subcomponent of the ASP.NET runtime with your own custom-written component.Implementing custom authentication or state services has never been easier.

Security

With built in Windows authentication and per-application configuration, you can be

assured that your applications are secure.ASP.NET is more than the next version of Active


25/52



Server Pages (ASP); it is a unified Web development platform that provides the services

necessary for developers to build enterprise-class Web applications. While ASP.NET is

largely syntax compatible with ASP, it also provides a new programming model and

infrastructure for more secure, scalable, and stable applications. You can feel free to augment

your existing ASP applications by incrementally adding ASP.NET functionality to

them.ASP.NET is a compiled, .NET-based environment; you can author applications in any

.NET compatible language, including Visual Basic .NET, C#, and JScript .NET.

Additionally, the entire .NET Framework is available toany ASP.NET application.

Developers can easily access the benefits of these technologies, which include the managed

common language runtime environment, type safety, inheritance, and so on. Each of these

models can take full advantage of all ASP.NET features, as well as the power of the .NET

Framework and .NET Framework common language runtime. These features and how you

can use them are outlined as follows.

If you have ASP development skills, the new ASP.NET programming model will

seem very familiar to you. However, the ASP.NET object model has changed significantly

from ASP, making it more structured and object-oriented. Unfortunately this means that

ASP.NET is not fully backward compatible; almost all existing ASP pages will have to be

modified to some extent in order to run under ASP.NET. In addition, major changes to Visual

Basic .NET mean that existing ASP pages written with Visual Basic Scripting Edition

typically will not port directly to ASP.NET. In most cases, though, the necessary changes will

involve only a few lines of code.

Accessing databases from ASP.NET applications is an often-used technique for

displaying data to Web site visitors. ASP.NET makes it easier than ever to access databases

for this purpose. It also allows you to manage the database from your code.ASP.NET

provides a simple model that enables Web developers to write logic that runs at the

application level. Developers can write this code in the global .asax text file or in a compiled

class deployed as an assembly. This logic can include application-level events, but developers

can easily extend this model to suit the needs of their Web application.

ASP.NET provides easy-to-use application and session-state facilities that are familiar

toASP developers and are readilylegal access to the security system can be avoided by

providing passwords for the handling personalities.

Time Delay in taking necessary access can be avoided as the user is instantly alerted.

Accuracy and perfection are the system s unique features.

It also provides reliable security system.

Manpower can be reduced considerably.

Thus the existing system can be improved and replaced by the computerization of the system

compatible with all other .NET Framework APIs.For advanced developers who want to use

APIs as powerful as the ISAPI programming interfaces that were included with previous

versions of ASP, ASP.NET offers the HttpHandler and HttpModule interfaces. Implementing

the HttpHandler interface gives you a means of interacting with the low-level. Request and

response services of the IIS Web server and provides functionality much like ISAPI

extensions, but with a simpler programming model. Implementing the HttpModule interfaceallows you to include custom events that participate in every request made to your

application.ASP.NET takes advantage of performance enhancements found in the .NET

Framework and common language runtime. Additionally, it has been designed to offer

significant performance improvements over ASP and other Web development platforms. All

ASP.NET code is compiled, rather than interpreted, which allows early binding, strong

typing, and just-in-time (JIT) compilation to native code, to name only a few of its benefits.

ASP.NET is also easily factorable, meaning that developers can remove modules (a sessionmodule, for instance) that are not relevant to the application they are developing. ASP.NET

also provides extensive caching services (both built-in services and caching APIs). ASP.NET

also ships with performance counters that developers and system administrators can monitor

to test new applications and gather metrics on existing applications.

The .NET Framework and ASP.NET provide default authorization and authentication

schemes for Web applications. You can easily remove, add to, or replace these schemes,

depending upon the needs of your application. ASP.NET configuration settings are stored in

XML-based files, which are human readable and writable. Each of your applications can have

a distinct configuration file and you can extend the configuration scheme to suit your

requirements.

ASP.NET ARCHITECTURE

As the illustration shows, all Web clients communicate with ASP.NET applications

through IIS.IIS deciphers and optionally authenticates the request. If Anonymous is turned

on, no authentication occurs. IIS also finds the requested resource (such as an ASP.NET

application), and, if the client is authorized returns the appropriate resource.In addition to the

built-in ASP.NET security features, an ASP.NET application can use the low-level security

features of the .NET Framework.

Integrating with IIS

IIS is the web server is used here. IIS 5.0 or above is essential for the ASP.NET. This

release of ASP.NET uses IIS 5.0 as the priKim host environment. When considering

ASP.NET authentication, you should understand the interaction with IIS authentication

services.IIS always assumes that a set of credentials maps to a Windows NT account and

uses them to authenticate a user. There are three different kinds of authentication available

in IIS 5.0

BASIC

DIGEST

INTEGRATED WINDOWS Authentication.

4.4 MICROSOFT SQL SERVER


28/52



Microsoft SQL Server is a relational database management system developed

by Microsoft. As a database, it is a software product whose primary function is to store and

retrieve data as requested by other software applications, be it those on the same computer orthose running on another computer across a network (including the Internet). There are at

least a dozen different editions of Microsoft SQL Server aimed at different audiences and for

differentworkloads (ranging from small applications that store and retrieve data on the same

computer, to millions of users and computers that access huge amounts of data from the

Internet at the same time). Its primary query languages are T-SQL and ANSI SQL.

SQL Server 2008

SQL Server 2008 (formerly codenamed "Katmai") was released on August 6,

2008 and aims to make data managementself-tuning, self-organizing, and self-maintaining

with the development of SQLServer Always On technologies, to provide near-zero

downtime. SQL Server 2008 also includes support for structured and semi-structured data,

including digital media formats for pictures, audio, video and other multimedia data. In

current versions, such multimedia data can be stored as BLOBs (binary large objects), but

they are generic bit streams. Intrinsic awareness of multimedia data will allow specialized

functions to be performed on them. According to Paul Flessner, senior Vice President, ServerApplications, Microsoft Corp., SQL Server 2008 can be a data storage backend for different

varieties of data: XML, email, time/calendar, file, document, spatial, etc. as well as

perform search, query, analysis, sharing, and synchronization across all data types.

Other new data types include specialized date and time types and a spatial data type for

location-dependent data. Better support for unstructured and semi-structured data is provided

using the new FILESTREAM data type, which can be used to reference any file stored on the

file system. Structured data and metadata about the file is stored in SQL Server database,whereas the unstructured component is stored in the file system. Such files can be accessed

both via Win32 file handling APIs as well as via SQL Server using T-SQL; doing the latter

accesses the file data as a BLOB. Backing up and restoring the database backs up or restores

the referenced files as well. SQL Server 2008 also natively supports hierarchical data, and

includes T-SQL constructs to directly deal with them, without using recursive queries.

29/52



The Full-text search functionality has been integrated with the database engine.

According to a Microsoft technical article, this simplifies management and improves

performance.

Spatial data will be stored in two types. A "Flat Earth" (GEOMETRY or planar)data type represents geospatial data which has been projected from its native, spherical,

coordinate system into a plane. A "Round Earth" data type (GEOGRAPHY) uses an

ellipsoidal model in which the Earth is defined as a single continuous entity which does not

suffer from the singularities such as the international dateline, poles, or map projection zone

"edges". Approximately 70 methods are available to represent spatial operations for the Open

Geospatial Consortium Simple Features for SQL, Version 1.1.

SQL Server includes better compression features, which also helps in improvingscalability. It enhanced the indexing algorithms and introduced the notion of filtered indexes.

It also includes Resource Governor that allows reserving resources for certain users or

workflows. It also includes capabilities for transparent encryption of data (TDE) as well as

compression of backups. SQL Server 2008 supports the ADO.NET Entity Framework and the

reporting tools, replication, and data definition will be built around the Entity Data

Model. SQL Server Reporting Services will gain charting capabilities from the integration of

the data visualization products from Dundas Data Visualization, Inc., which was acquired byMicrosoft.

4.5 WINDOWS 7

Windows 7 is an operating system produced by Microsoft for use on personal

computers, including home and business desktop, laptops, netbooks, tablet PCs, and media

center PCs. It was released to manufacturing on July 22, 2009, and became generally

available retail worldwide on October 22, 2009, less than three years after the release of its predecessor, Windows Vista. Windows 7's server counterpart, Windows Server 2008, was

released at the same time. Windows 7 is succeeded by Windows 8.

Unlike Windows Vista's many new features, Windows 7 was an incremental upgrade

designed to work with Vista-compatible applications and hardware. Mail, Windows Movie

Maker, and Windows Photo Gallery, are not included in Windows most are instead offered

separately at no chargeas part of the suite.

5. SYSTEM TESTING AND IMPLEMENTATION

After finishing the project we have to test the project in a selected environment

with given conditions and for that specific strategy has to be made also implementation state

in which the completed project have to be implemented to different system and check its

functionality.

5.1. SYSTEM TESTING

System Testing

System testing of software or hardware is testing conducted on a complete, integrated

system to evaluate the system's compliance with its specified requirements. System testing

falls within the scope of black box testing, and as such, should require no knowledge of the

inner design of the code or logic.

As a rule, system testing takes, as its input, all of the "integrated" software

components that have successfully passed integration testing and also the software system

itself integrated with any applicable hardware system(s). The purpose of integration testing is

to detect any inconsistencies between the software units that are integrated together (called

assemblages) or between any of the assemblages and the hardware. System testing is a more

limited type of testing; it seeks to detect defects both within the "inter-assemblages" and also

within the system as a whole.

Software Testing

Software testing is an important phase in the development of the system. Generally,system testing involves testing integration of each module in the system. The objective while

testing the system is to test the discrepancies between the system and the original objective.

The quality of an information system depends on its design, development, implementation

and design.Testing is the most important activity in the development phase. Testing is the

process of finding errors or bugs in the system. Testing ensure that the user needs are

satisfied. In other words it is a process by which one detects the defects in the system.


31/52



Software testing methods are traditionally divided into black box testing and white

box testing. These two approaches are used to describe the point of view that a test engineer

takes when designing test cases.

Black box testing treats the software as a black-box without any understanding of

internal behavior. It aims to test the functionality according to the requirements. Thus, the

tester inputs data and only sees the output from the test object. This level of testing usually

requires thorough test cases to be provided to the tester who then can simply verify that for a

given input, the output value (or behavior), is the same as the expected value specified in the

test case. Black box testing methods include: equivalence partitioning , boundary value

analysis, all-pairs testing, fuzz testing, model-based testing, traceability matrix etc.

White box testing, however, is when the tester has access to the internal data

structures, code, and algorithms. White box testing methods include creating tests to satisfy

some code coverage criteria. For example, the test designer can create tests to cause all

statements in the program to be executed at least once. Other examples of white box testing

are mutation testing and fault injection methods. White box testing includes all static testing.

This testing is based on knowledge of the internal logic of an application s code. Also known

as Glass box Testing. Internal software and code working should be known for this type of

testing. Tests are based on coverage of code statements, branches, paths, conditions.

There are many approaches to software testing. Reviews, walkthroughs or inspections

are considered as static testing, whereas actually running the program with a given set of test

cases in a given development stage is referred to as dynamic testing.

Software testing is used in association with verification and validation:

Verification: Have we built the software right

Validation:Have we built the right software

The different types of testing are:

Unit Testing

Integration Testing

Validation Testing

System Testing

Output Testing


32/52



Unit Testing

In computer programming, unit testing is a procedure used to validate that

individual units of source code are working properly. A unit is the smallest testable part of anapplication. In procedural programming a unit may be an individual program, function,

procedure, etc., while in object-oriented programming, the smallest unit is a method, which

may belong to a base/super class, abstract class or derived/child class.

Ideally, each test case is independent from the others; mock or fake objects as well

as test harnesses can be used to assist testing a module in isolation. Unit testing is typically

done by software developers to ensure that the code they have written meets software

requirements and behaves as the developer intended.

In this we test each module individually but not integrate the whole system. It

focuses verification efforts even in the smallest unit of software design in each module. This

is also known as Module Testing. The testing is carried out in the programming style itself.

In this testing each module is focused to work satisfactorily as regard to the expected output

from the module. There are some validation checks for the fields.

Integration Testing

Integration testing (sometimes called Integration and Testing, abbreviated I&T) is

the phase of software testing in which individual software modules are combined and tested

as a group. It follows unit testing and precedes system testing.Integration testing takes as its

input modules that have been unit tested, groups them in larger aggregates, applies tests

defined inan integration test plan to those aggregates, and delivers as its output the integrated

system ready for system testing.

Data can be lost across an interface, one module can have adverse effect on the

other sub-functions, when combined may not produce the desired functions. Integration

testing is the systematic testing to uncover the errors within the interface. This testing is done

with simple data .The need for an integrated system is to find the overall performance.

The purpose of integration testing is to verify functional, performance and

reliability requirements placed on major design items. These "design items", i.e. assemblages

(or groups of units), are exercised through their interfaces using black box testing, success

and error cases being simulated via appropriate parameter and data inputs. Simulated usage of

shared data areas and inter-process communication is tested and individual subsystems are


33/52



exercised through their input interface. Test cases are constructed to test that all components

within assemblages interact correctly, for example across procedure calls or process

activations, and this is done after testing individual modules, i.e. unit testing.

Validation Testing

At the culmination of black box testing (Here the structure of the program is not

considered),software is completely assembled as a package.Interface errors have been

uncovered and correct and final series of tests, i.e., and validation test begins. The customer

defines validation with a simple definition and validation succeeds. When the software

functions in manner than can be reasonably accepted.

Recovery testing

In this test method we are concerned with the software s ability to retrieve lost data or

to make sure that software does not lose any data during the updating of the database. We

will be mainly looking at transaction processing when we talk about the recovering testing. In

transaction protection we will be testing the software to make sure that when it saves

anything it will save all of it or none of it. This is necessary to avoid existence of corrupt datain database.

Security testing

In this testing section we are concerned about the security of the software. We will be

testing the software to see if unauthorized users are able to access sensitive parts of the

software. We have divided the security section in three stages.

Password Login

We will try to log in using invalid user name or valid user name and invalid password.

We will also test the software to see if it allows access without any identification. We will

also test the software so that password is not saved in any way within computer for others to

view.


34/52



Modular Access

Our software identifies the user and allows him or her to access only certain modules.

We will test to see if the software restricts unauthorized users from accessing certain modules

of the software. In particular we want to make sure that user cannot access modules for the

administrator.

Priority Access

Priority access is not of a serious concern since this system is only used by

theadministrator who has the sole ownership of the system.

Stress testing

In this test method we are concerned with the software s ability to allow concurrent

transaction. Too much of the work at the same time may cause system shutdown or frees. We

want to test and to make sure that this does not happen. As test procedure we will try to create

as much traffic for the software as we can by opening several applications concurrently. We

should not have any trouble in achieving our goal in this section of the test since our product

is not at the large-scale software products and does not generate too much traffic either.

WhiteBox Testing

White-box testing (also known as clear box testing, glass box testing, transparent

box testing, and structural testing) is a method of testing software that tests internal structures

or workings of an application, as opposed to its functionality (i.e. black-box testing). In

white-box testing an internal perspective of the system, as well as programming skills, arerequired and used to design test cases. The tester chooses inputs to exercise paths through the

code and determine the appropriate outputs. This is analogous to testing nodes in a circuit,

e.g. in-circuit testing (ICT).

While white-box testing can be applied at the unit, integration and system levels of

the software testing process, it is usually done at the unit level. It can test paths within a unit,

paths between units during integration, and between subsystems during a system level test.

Though this method of test design can uncover many errors or problems, it might not detectunimplemented parts of the specification or missing requirements.

White box test design techniques include

Control flow testing

Data flow testing Branch testing Path testing

Testing Tools And Environment

Test Schedule

Test Plan Creation 4 days

Unit Testing 3 days

Integration Testing 2 days

System Testing 4 days

Performance Testing 2 days

Validation Testing 2 days

Test Procedure

This section describes as detailed test procedure including test tactics and test case for

the software.

Unit test cases

In this method of testing we will test the smallest unit of software called modules.

We will be testing all the important paths to find any errors within the boundary of module.So here white box search is applied. We will be testing parts of the software rather than the

entire software. The modules are as follows.

Blackbox Testing


36/52



Black-box testing is a method of software testing that tests the functionality of an

application as opposed to its internal structures or workings (see white-box testing). Specific

knowledge of the application's code/internal structure and programming knowledge in

general is not required. Test cases are built around specifications and requirements, i.e., what

the application is supposed to do. It uses external descriptions of the software, including

specifications, requirements, and designs to derive test cases. These tests can be functional or

non-functional, though usually functional. The test designer selects valid and invalid inputs

and determines the correct output. There is no knowledge of the test object's internal

structure.

This method of test can be applied to all levels of software testing: unit, integration,

functional, system and acceptance. It typically comprises most if not all testing at higher

levels, but can also dominate unit testing as well.

Typical black-box test design techniques include

Decision table testing

All-pairs testing

State transition tables

Equivalence partitioning Boundary value analysis.

System Testing

When a system is developed it is hoped that it performs properly. In practice

however some errors always occur. The main purpose of testing an information system is to

find the errors and correct them. A successful test is one which finds an error. The main

objectives of the system testing are To ensure during operation the system will perform as per specification.

To make sure that the system meets user requirements during operation.

To verify that the controls incorporated in the system function as intended.

To see that when correct inputs are fed to the system and the outputs are correct.

To make sure that during operation incorrect input processing and output will be

deleted.


37/52



Software testing is a critical element of software quality assurance and represents

the ultimate review of specification, design and coding. If the testing conducted successfully,

it will uncover errors in the software. As a secondary benefit, testing demonstrates that the

software functions appear to be working according to specification and thatperformance

requirements appear to have been made.

The scope of the systemtestshouldincludebothmanualoperations and computer

operationssystemtestingiscomprehensive evaluation of the programs manual procedures,

computer operations and control.

System testing is the process of checking if the developed system is working

according to the original objectives and requirements. All the testing needs to be conducted

in accordance to the test conditions specified earlier.

Unit testing

In this test focus on each modules meandering User Management, Web Services,

Mail, SMS, Feedback of the system individually, ensuring that it function properly as an

individual unit according to solve the requirement of a particular module. In unit testing

control path are tested to uncover errors in the boundary of the module.

Integration testing

Here this Integration testing is done by assembling Web Services, Mail,

SMStogether. This Systematic technique for constructing the program structure while at the

same time conducting test to uncover errors to associate with interfacing.

Acceptance testing

The system is validated by negotiating the existing and proposed system. This test

evaluates the system in the real time environment with live data and finds it to be satisfied.

This is done by the user. The various possibilities of the data are entered and response from

the system is tested once the acceptance testing is signed off by the user.


38/52



5.2. SYSTEM IMPLEMENTATION

Implementation is the realization of an application, or execution of a plan, idea,

model, design,specification,standard, algorithm or policy.In computer science, an

implementation is a realization of a technical specification or algorithm as

a program, software component, or other computer system through computer

programming and deployment. Many implementations may exist for a given specification or

standard. For example, web browsers contain implementations of World Wide Web

Consortium-recommended specifications, and software development tools contain

implementations of programming languages.

Types of implementation:

Direct changeover

Parallel running or as known as parallel

Pilot introduction or as known as pilot

Well-trade

After the system has been tested, the implementation type or the changeover

technique from the existing system to the new system is a step-by-step process. In the system

at first only a module of the system is implemented and checked for suitability andefficiency. When the end user related to the particular module is satisfied with the

performance, the next step of implementation is preceded.Implementation to some extent is

also parallel. For instance, modules which are not linked, with other modules are

implemented parallel and the training is the step-by -step process.

Backups are necessary since any time unexpected events may happen. And so during

the program execution, the records are stored in the workspace. This helps to recover the

original status of the records from any accidental updation or intentional deletion of records.

5.3 SYSTEM MAINTENANCE

Maintenance of the software is one of major step in the computer animation.

Software which is developed by the engineer, should undergo maintenance process in regular

interval of time goes on new problems arise and it must be corrected accordingly.

Maintenance and enhancement are a long term process.


39/52



In this project, the maintenance is carried over by the staff concern. Since they are

the key persons to develop this project they know clearly about the project and coding

structure. So, they will change the coding whenever required. Regarding the project

maintenance, the changes will occur then and there according to the conditions.

Various types of maintenance that can be made are:

Corrective maintenance

Adaptive maintenance

Prefecture maintenance

Reverse engineering

Re engineering

The staff in the concern are parted each and every level of the project. So they

don t need any training of the software. During the development process they sit and entered

each and every entry to test the project. They themselves used this is an opportunities to take

training in the software so extra training is not needed for the user.

7. CONCLUSION


51/52



The SMS BASED SYSTEM SCHEDULING SYSTEM has been developed for

the benefit of controlling systems by sending message from a mobile phone. This system is

more advanced than existing system. The system is very user friendly, so the user with

minimum knowledge about the computer is able to operate the system easily.

This application makes it easier to control system operations like device control,

setting reminders for specified tasks etc. The operations can easily be controlled from a

remote area whe

re GSM network is available. For this application to run no internet connection is

required. Here we just require a SMS service enabled phone. And it is through mobile that we perform all the system operations

The system has been developed and is found working effectively. The developed

system is flexible and changes can be made easy as and when required. Itried to make the

system maximum user friendly. The system is protected from any unautherized access by

giving password during log in process. All the necessary validations are carried out in this

project..

This system uses C# as front end and sqlserver as back end. This system is made

operational after understanding a series of phases namely study phase, design phase,

development phase. It is very user friendly and a nonprogrammer can use the system very

easily.

The project is based on the requirement specification of the user and the analysis of

the existing system, with flexibility for future enhancement. Since the system is developed in

modules, future enhancement is very easy.
