2/81

Mailing system is a very useful application that is used for the communication purposes

of educational institutions. The application is developed using ASP.Net and C#, with sql server

as the back end. There are two modules in this application. They are users and administrators.

The administrators have full access to the application i.e. the administrator can access all of the

modules in the application, while the users have restricted access that is they can use only some

of the modules.

The purpose of this project is to create an application for a university. So that

communication among different departments is possible. The proposed system is to create a

mailing system such that each user (Employee of the university) will have access to the

application according to their roles, create their own mail-ids and can use this id to

communicate with other users in the university.

This project comprises of two modules:

1. Administrator module.

2. User module.

1. Administrator Module:

This application deals with database maintenance and differentiating users

according to their roles, the administrator has privileges to delete any user at any point of time.

2. User module:

In this module, the users (Employee of the university) will create own mail-ids

and can have all mailing facilities.

Each module in their application consists of their own authentication and can view/enter

the details as when required. This application also deals with the security in order to make the

application secured. It uses the authentication techniques to provide role-based security. In order

to make the database consistent, necessary steps are taken while creating the database. The

exception handling techniques are used to provide code based security to prevent the application

from abnormal termination.

Framework : .Net Framework

Back- End : MS SQL SERVER

IDE : Microsoft Visual studio

Web Technology : ASP.NET

Web Server : IIS

Language : C# .NET

Project will be done in ASP. NET with C# as front end and SQL Server 2005 as back end.

Microsoft .NET is framework that connects information, people, systems and devices. It spans

clients, servers and developer tools and consists of:

The .NET Framework programming model that enables developers to build Web-

based applications which expose their functionality programmatically over a

network using standard protocols such as HTTP.

5/81

Developer tools such as Microsoft Visual Studio .NET, which provide a rapid

application integrated development environment for programming with the .NET

Framework.

Client software such as Windows XP, Windows CE and Microsoft Office XP that

helps developers deliver a deep and compelling user experience across a family of

devices and existing products.

The .NET Framework is the programming model of the .NET environment for building,

deploying and running Web- based applications, smart client applications and XML Web

services. It manages much of the plumbing, enabling developers to focus on writing the business

logic code for their applications. The .NET Framework includes the common language runtime

and class libraries.

ORGANIZATIONAL

PROFILE

Krishna University largely caters to the higher educational needs of people in Krishna

District in particular and Andhra Pradesh in general. Krishna district was one of the oldest

British administered areas of Andhra Pradesh. It was formerly called Masulapatnam district, and

in1859 when the then Guntur district was delinked, certain taluks, thereof, were added to this,

which was renamed as Krishna district, after the mighty river Krishna. This district is endowed

6


7/81

with a rich variety of soils, and occupies an important place in agriculture. This district is also

known for the availability of mineral sources like Chromites, Diamonds, Iron ore, Limestone,

Mica and Sulphur. This district has a geographical area of 8727 Sq Mt with a population of

around 42 lakhs. This District is endowed with one of the largest fresh water lakes called Kolleru

Lake.

Krishna University is established in a great historic coastal town called Machilipatnam,

which are the head quartos of Krishna district of Andhra Pradesh. Machilipatnam is a city and a

special grade municipality in Krishna district in Indian state of Andhra Pradesh

Krishna University is presently located at Andhra Jateeya kalasala, a famous first grade

college in Machilipatnam. The university will function from the academic year 2008-09 in the

academic blocks of A.J Kalasala Campus allotted for this purpose.

SYSTEM ANALYSIS

4.1 DEFINITION

System Analysis is the detailed study of the various operations performed by the system

and their relationships within and outside the system. Analysis is the process of breaking

something into its parts so that the whole may be understood. System analysis is concerned with

becoming aware of the problem, identifying the relevant and most decisional variables, analyzing

8


9/81

and synthesizing the various factors and determining an optimal or at least a satisfactory

solution. During this a problem is identified, alternate system solutions are studied and

recommendations are made about committing the resources used to design the system

4.2 PROPOSED SYSTEM

Mailing System is aimed at developing a web-based and central process system for

communication purposes in Educational institutions. Some features of this system will be storing

mails, replies to the mails, composing mails, sending attachments, etc.

4.3 ADVANTAGES

Speed: As the application is developed on Local Net, the messages are delivered

instantly resulting fast communication.

Easy to prioritize: Since the mails have subject lines, it is easy to prioritize them and

ignore unwanted mails.

Reliable and secure: Constant efforts are being taken to improve the security in

electronic mails. Thus making it one of the secured ways of communication.

Informal and conversational: The language used in e-mails is generally simple and thus

makes the communication informal. Sending and receiving e-mails takes less time, so it can be

used as a tool for interaction.

4.4 FEASIBILTY STUDY

A feasibility analysis usually involves a through assessment of the operational (need),

financial and technical aspects of a proposal. Feasibility study is the test of the system proposal

made to identify whether the user needs may be satisfied using the current software and

hardware technologies, whether the system will be cost effective from a business point of view

and whether it can be developed with the given budgetary constraints. A feasibility study should

9


10/81

be relatively cheap and done at the earliest possible time. Depending on the study, the decision is

made whether to go ahead with a more detailed analysis.

When a new project is proposed, it normally goes through feasibility assessment.

Feasibility study is carried out to determine whether the proposed system is possible to develop

with available resources and what should be the cost consideration. Facts considered in the

feasibility analysis were.

Technical Feasibility

Economic Feasibility

Behavioral Feasibility

4.4.1 Technical Feasibility

Technical feasibility includes whether the technology is available in the market for

development and its availability. The assessment of technical feasibility must be based on an

outline design of system requirements in terms of input, output, files, programs and procedures.

This can be qualified in terms of volumes of data, trends, frequency of updating, cycles of

activity etc, in order to give an introduction of technical system. Considering our project if is

technically feasible. Internal Management System with its emphasis on a more strategic decision

making is fast gaining ground as a popular outsourced function.

4.4.2 Economical Feasibility

This feasibility study present tangible and intangible benefits from the prefect by

comparing the development and operational cost. The technique of cost benefit analysis is often

used as a basis for assessing economic feasibility. This system needs some more initial

investment than the existing system, but it can be justifiable that it will improve quality of

service.

10


11/81

Thus feasibility study should center along the following points:

Improvement resulting over the existing method in terms of accuracy, timeliness.

Cost comparison

Estimate on the life expectancy of the hardware

Overall objective

Our project is economically feasible. It does not require much cost to be involved in the overall

process. The overall objectives are in easing out the requirement processes.

4.4.3 Behavioral/ Operational Feasibility

This analysis involves how it will work when it is installed and the assessment of

political and managerial environment in which it is implemented. People are inherently resistant

to change and computers have been known to facilitate change. The new proposed system is very

much useful to the useful to the users and there for it will accept broad audience from around the

world.

11

SYSTEM DESIGN

5.1 DEFINITION

The most creative and challenging face of the system development is System Design. It

provides the understanding and procedural details necessary for implementing the systemrecommended in the feasibility study. Design goes through the logical and physical stages of

development.

In designing a new system, the system analyst must have a clear understanding of the

objectives, which the design is aiming to fulfill. The first step is to determine how the output is to

12


13/81

be produced and in what format. Second, input data and master files have to be designed to meet

the requirements of the proposed output. The operational phases are handled through program

construction and testing.

Design of a system can be defined as a process of applying various techniques and

principles for the purpose of defining a device, a process or a system in sufficient detail to permit

its physical realization. Thus system design is a solution to how to approach to the creation of

a new system. Thus important phase provides the understanding and the procedural details

necessary for implementing the system recommended in the feasibility study. The design step

provides a data design, architectural design, and a procedural design.

5.2 OUTPUT DESIGN

In the output design, the emphasis is on producing a hard copy of the information

requested or displaying the output on the CRT screen in a predetermined format. Two of the

most output media today are printers and the screen. Most users now access their reports from a

hard copy or screen display. Computers output is the most important and direct source of

information to the user, efficient, logical, output design should improve the systems relations

with the user and help in decision-making.

As the outputs are the most important source of information to the user, better design

should improve the systems relation and also should help in decision-making. The output

devices capability, print capability, print capability, response time requirements etc should also

be considered form design elaborates the way output is presented and layout available for

capturing information. Its very helpful to produce the clear, accurate and speedy information for

end users.

5.3 INPUT DESIGN

In the input design, user-oriented inputs are converted into a computer based system

format. It also includes determining the record media, method of input, speed of capture and

entry on to the screen. Online data entry accepts commands and data through a keyboard. The

13


14/81

major approach to input design is the menu and the prompt design. In each alternative, the users

options are predefined. The data flow diagram indicates logical data flow, data stores, source and

destination. Input data are collected and organized into a group of similar data. Once identified

input media are selected for processing.

In this software, importance is given to develop Graphical User Interface (GUI), which is

an important factor in developing efficient and user-friendly software. For inputting user data,

attractive forms are designed. User can also select desired options from the menu, which

provides all possible facilities.

Also the important input format is designed in such a way that accidental errors are

avoided. The user has to input only just the minimum data required, which also helps in avoiding

the errors that the users may make. Accurate designing of the input format is very important in

developing efficient software. The goal or input design is to make entry as easy, logical and free

from errors.

5.4 SOFTWARE DESIGN

It is a process of planning the new or modified system. Analysis specifies what a

new or modified system does. Design specifies how to accomplish the same. Design is

essentially a bridge between requirement specification and the final solution satisfying the

requirements. Design of a system is essentially a blue print or a solution for the system.

The design process for a software system has two levels. At first level the focus is

on depending in which modules are needed for the system, the specification of these modules

and how the modules should be interconnected. This is what is called system designing of top

level design. In the second level, the internal design of the modules, or how the specification of

the module can be satisfied is described upon. This design level is often called detailed design or

logic design.

14


15/81

The first level produces system design, which defines the components needed for

the system, and how the components interact with each other. It focus is on depending on in

which that modules are needed for the system, the specification of these modules and how the

module should be interconnected.

5.4.1Introduction to UML

Unified Modeling Language is the one of the most exciting tools in the world of

system development today. Because UML enables system builders to create blue prints that

capture their visions in a standard, easy to understand way and communicate them to others.

The UML is brain child of Grady Brooch, James Rumbaugh and Ivar Jacobson.

The UML is a language for

Visualizing

Specifying

Constructing

Documenting

These are the artifacts of a software-intensive system. The abbreviation for UML

is Unified Modeling Language and is being brought of a designed to make sure that the existing

ER Diagrams which do not serve the purpose will be replaced by this UML Diagrams where in

these language as its own set of Diagrams.

Some of the Diagrams that help for the Diagrammatic Approach for the Object

Oriented Software Engineering are:

Class Diagrams

Use Case Diagrams

Sequence Diagrams

State Chart Diagrams

Activity Diagrams

15


16/81

Using the above mentioned diagrams we can show the entire system regarding the

working of the system or the flow of control and sequence of flow the state of the system and the

activities involved in the system.

5.4.2 Components of the UML:

The UML consists of a number of graphical elements that combine to form

diagrams. Because its a language, the UML has rules for combining these elements. The

purpose of the diagrams to present multiple views of the system, and this set of multiple views is

called a Model. A UML Model of a system is something like a scale model of a building. UML

model describes what a system is supposed to do. It doesnt tell how to implement the system.

The following are the main nine component Diagrams of UML:

5.4.3 Class Diagram:

A Class is a category or group of things that has similar attributes and common

behavior. A Rectangle is the icon that represents the class it is divided into three areas. The upper

most area contains the name, the middle area contains the attributes and the lowest areas show

the operations. Class diagrams provides the representation that developers work from. Class

diagrams help on the analysis side, too.

5.4.4 Object Diagram:

An object is an instance of a class- A specific thing that has specific values of the

attributes and behavior. A Rectangle is the icon that represents the object diagram but the name

is underlined. The name of the specific instance is on the left side of the colon, and the name of

the class is on the right side of the colon .

5.4.5 Use-Case Diagram:

A Use-Case is a description of a systems behavior from a users stand point. For

system developer this is a valuable tool: its a tried-and-true technique for gathering system

requirements from a users point of view. That is important if the goal is to build a system that

16


17/81

real people can use. A little stick figure is used to identify an actor the ellipse represents use-

case.

5.4.6 State Diagram:

At any given time, an object is in particular state. One way to characterize change

in a system is to say that its objects change the state in response to events and to time. The UML

State Diagram captures these kinds of changes it presents the states an object can be in along

with the transitions between the states, and shows the starting point and end point of a sequence

of state changes.

A Rounded Rectangle represents a state, along with the solid line and arrow head

that represents a transition. The arrow head points to the state being transition into. The solid

circle symbolizes starting point and the bulls eye that symbolizes the end point.

5.4.7 Sequence Diagrams:

In a functioning system objects interacts with one another and these interactions

occur over time. The UML Sequence Diagrams shows the time based dynamics of the

interaction. The sequence diagrams consist of objects represented in the usualway-as named

rectangles (If the name underlined), messages represented as solid line arrows and time

represented as a vertical progression.

5.4.8 Activity Diagrams:

The state diagram shows the states of an object and represents activities as arrows

connecting the states. The Activity Diagram highlights the activities. Each activity is represented

by a rounded rectangle-narrower and more oval-shaped than the state icon. An arrow represents

the transition from the one activity to the next. The activity diagram has a starting point

represented by filled-in circle, and an end point represented by bulls eye.

5.4.9 Collaboration Diagram:

17


18/81

An object diagram shows the objects and their relationships with one another. A

collaboration Diagram is an extension of the object diagram. In addition to the associations

among objects, the collaboration diagram shows the messages the objects and each other.

5.5 Use cases:

Use case Model:

The functional model, represented in UML with use case diagrams,

describes the functionality of the system from the users point of view. Use cases are

used during requirements elicitation and analysis to represent the functionality of the

system. A use case describes a function provided by the system that yields a visible result

for an actor. An actor describes any entity that interacts with the system. An actor can be human

or an external system. In this proposed system actors are Administrator, Manager, Technical

person and Customer.

USE CASE DIAGRAMS:

UML provides the use case diagram to facilitate the process of requirements

gathering. The Use case diagram models the interactions between the systems external clients

and the use cases of the system.

21/81

The object model, represented in UML with Class diagrams, Describes the

structure of system in terms of objects, attributes, associations.

The UML enables us to model the classes in a system and their relationships via class

diagrams. In a class diagram, each class is modeled as a rectangle. This rectangle can be divided into

three parts. The top part contains the name of the class. The middle part contains the classs attributes.

The bottom contains the classs operations. The UML defines object diagrams which are similar to class

diagrams except that they model objects and links-links are relationships between objects. Object

diagrams present a snapshot of the structure while the system is running this provides information about

which objects are participating in the system at a specific point in time.

TESTING

Testing is a process to show the correctness of the program. Testing is needed to show

completeness, improve the quality of the software and to provide the maintenance aid. Some

testing standards are therefore necessary reduce the testing costs and operation time. Testing

software extends throughout the coding phase and it represents the ultimate review of

configurations, design and coding. Based on the way the software reacts to these testing, we can

decide whether the configuration that has been built is study or not. All components of an

application are tested, as the failure to do so many results in a series of bugs after the software

put to use.

52


53/81

8.1 Black box Testing

Black box testing, also called behavioral testing, focuses on the functional requirements of

software. This testing approach enables the software engineer to derive the input conditions that

will fully exercise all requirements for a program. Black box testing attempts to find the errors

like

Incorrect or missing functions

Interface errors

Errors in data structures or external database access

Behavior or performance errors

Initialization and termination errors

In Black box testing software is exercised over a full range of inputs and outputs are observed for

correctness.

8.2 White box Testing

White box testing is also called Glass box testing is a test case design control; structure of

the procedural design to derive test cases using White box testing method, the software engineer

can derive the test cases that guarantee that all independent paths within the module have been

exercised at least once. Exercise all logic decisions on their true or false sides. Execute all loops

at their boundaries and within their operational bounds. Exercise internal data structure to ensure

their validity.

8.3 Software Testing Strategies

Testing involves

Unit testing

Integration testing

Acceptance testing

53


54/81

The first level of test is unit testing. The purpose of unit testing is to ensure that each

program is fully tested.

The second step is integration testing. In this individual program units or programs are

integrated and tested as a complete system to ensure that the software requirements are met.

Acceptance Testing involves planning and the execution of various types of tests in order

to demonstrate that the implemented software system satisfies the requirements. Finally our

project meets the requirements after going through all the levels of testing.

71/81

The Mailing System was developed with an aim of making the communication faster

among different departments in bigger institutions. It meets the needs of several facilities not

only passing messages but also sending larger files from one location to another through a local

area network, thus by resulting time saving and accuracy.

MICROSOFT VISUAL STUDIO

Microsoft Visual Studio is Microsofts flagship software development product for

computer programmers. It centers on an integrated distribution environment which has

programmers create stand alone, and web services that run on any platforms supported by

Microsofts .Net Framework (for all versions after 6). Supported platforms include Microsoft

windows, servers and workstations, Pocket PC, Smart Phones and World Wide Web browsers

not the Java Virtual Machine that all other java tools target.

VISUAL STUDIO 2008

The most important language added in this version was the introduction of generics,

which are similar in many aspects to C++ templates. This potentially increases the number of

bugs caught at compile- time instead of runtime by encouraging the use of strict type checking

in areas where it was not possible before, C++ also got a similar upgrade with the addition of C+

+/CLI which is slated to replace the use of Managed C++. Other new features of Visual Studio

2005 include the Development Designer which allows application designs to be validated

before deployments, an improved environment for web publishing when combined with

ASP.NET 2.0 and load testing to see application performance under various sorts of user loads.

Visual Studio 2008 also added extensive 64- bit support. While the development environment

itself only available as a 32- bit application, visual C++ 2008 supports compiling for

(x64AMD64 and EM64T) as well as IA- 64 (Itanium). The platforms SDK include 64- bit and

64-bit versions of the libraries.

NET FRAMEWORK SDK

The .NET framework is an integral windows component that supports building and

running the next generation of applications and XML web services. The key component of the

.NET frame work are the common language run time and the . NET frame work class library,

which includes ADO.NET, ASP.NET and windows forms. The .NET framework provides a

managed execution environment simplified development and deployment and integration with a

wide variety of programming languages.

This framework is made up of the following parts:

The common language runtime(CLR)

The base class libraries.

Rich client user interface using windows forms

RAD for the internet using web forms

OVERVIEW OF THE .NET FRAME WORK

The .NET framework is a new computing platform that simplifies application

development in the highly distributed environment of the internet. The .NET framework is

designed to fulfill following objectives:

To provide a consistent object oriented programming environment whether object

code is stored and executed locally but internet- distributed or executed remotely.

To provide a code execution environment that minimizes software deployment

and versioning conflicts.

To provide a code execution environment that guarantees safe execution of code,

including code created by an unknown or semi trusted third party.

74


75/81

To provide a code execution environment that eliminates the performance

problem of scripted or interpreted environments.

To make the developer experience consistent across widely types of application, such as

windows based applications and web based applications.

To build all communication on industry standards to ensure that code based on the .NET

framework can integrate with any other code.

The .NET framework has two main components: the common language runtime and

the .Net framework class library. The common language runtime is the foundation of the .NET

framework. You can think of the runtime as an agent that manages code at execution time, and

remoting while also enforcing strict type safely and other forms of code accuracy that ensure

security and robustness in fact the concept of code management is a fundamental principle of the

runtime.

Code that targets the runtime is known as managed code, while code that does not

target the runtime is known as un managed code. The class library, the other main component of

the .NET frameworks is a comprehensive, object-oriented collection reusable types that you can

use to develop applications ranging from traditional command line or graphical user interface

(FGUI) applications to application base d on the latest innovations provided by ASP.NET, such

as web forms and XML web services.

The .NET framework can be hosted by unmanaged component that load the common

language runtime into their processes and initiate the execution of managed code. ASP.NET

works directly with the runtime to enable ASP.NET application and XML web services, both of

which are discussed later in this topic, Internet explorer is an example of unmanaged application

that hosts the runtime (in the form of a MIME type extension). Using internet explorer to the

host runtime enables you to embed managed components or windows forms controls in HTML

documents. Hosting the runtime in this way makes mobile code 9similar to Microsoft Active Xr

controls) possible, but with significant improvement that only managed code can offer, such as

semi-trusted execution and secure isolated file storage.

75


76/81

The following illustration shows the relationship of the common language runtime and

the class library to your application and to the overall system. The illustration also shows how

managed code operated with in a larger architecture.

We can use the .NET framework to develop the following types of application and services:

Console applications

Web applications

XML Web services

Windows Forms Applications

COMMON LANGUAGE RUNTIME (CLR)

The common language runtime (CLR) is responsible for runt-time services such as

language integration; security enforcement; and memory, process and thread management. In

addition, it has a roll at development time when features such as life cycle management strong

type naming, cross-language exception handling, dynamic binding and so on, reduce the amount

of code that a developer must write to turn the business logic the reusable component. The

runtime can be hosted by high performance, server-side applications, such a s Microsoft Internet

Information Services (IIS) for building web applications with ASP.NE and the next release of

Microsoft SQL Server. This infrastructure enables you to use code managed by the .NET

framework to write your business logic, while still enjoying the superior performance of the

industrys best enterprises servers that support runtime hosting.

76


77/81

ASP.NET

ASP.NET is a set of Microsoft.NET framework technologies used for building web

applications and XML Web services. ASP.NET page execute on the server and generate mark

up such as HTML, WML or XML that is sent to a desktop or mobile browser. ASP.NET pages

use a compiled, event-driven programming model that improves performance and enables the

separation of application logic and user interface. Both ASP.NET pages and ASP.NET web

services files contain server-side (as opposed to client side logic) written in Visual basic .NET,

C#.NET or any .NET compatible language, Web applications and XML Web Services take

advantage of the features of the common language runtime, such as type safety, inheritance,

language, interoperability, versioning, and integrated security.

IIS

Microsoft Internet Information S4ervices (IIS; formerly called Server is a set of

Internet-based services for servers using Microsoft Windows. It is the worlds second most

popular web server in terms of overall websites. As of September 2007 it served 34.94% of all

websites and 36.63% of all active websites according to Net craft. The servers currently include

FTP, SMTP, NNTOP, and HTTP/HTTPS.

ADO.NET

ADO.NET provides consistent access to data sources such a Microsoft SQL Server and

XML, as well as to data sources exposed through OLE DB and ODBC. Data sharing consumer

applications can use ADO.NET to connect to these data sources and retrieve, manipulate and

update the data that they contain.ADO.NET separates data access from data manipulation into discrete components that

can be used separately or in tandem. ADO.NET includes .NET Frame work data providers for

connecting to a database, executing commands and retrieving results. Those results are either

processed directly, placed in and ADO.NET Dataset objects in order to be exposed to the used in

an ad hoc manner, combined with data from multiple sources or remoted between tiers.

77


78/81

The ADO.NET Dataset object can also be used independently of a .NET Framework data

provider to manage data local to the application or sourced from XML.

The ADO.NET classes are found in System.Data.dll and are integrated with the XML

classes found in System.Xml.dll. When compiling code that uses the System. Data, namespace

reference both System.Data.dll and System.Xml.dll.

ADO.NET provided functionality to developers writing managed code similar to the

functionality provided to native component object model (COM) developers by ActiveX Data

Objects (ADO).

ADO.NET COMPONENTS

There are two components of ADO.NET that you can use to access and manipulate

data:

.NET Framework data providers.

The Dataset

.NET FRAMEWORK DATA PROVIDERS

The .NET Framework Data providers are components that have been explicitly

designed for data manipulation and fast, forward-only, read-only access to data. The connection

object provides connectivity to a data source. The command object enables access to database

commands to return data, modify data, run stored procedures and send or retrieve parameter

information.

The Data Adapter provides a high-performance stream of data from the data source.

Finally, the Data Adapter provides the bridge between the Dataset object and the data source.

The Data Adapter uses command object to execute SQL commands at the data source to both

load the Dataset with data and reconcile changes made to the data in the Dataset back to the data

source.

78


79/81

THE DATASET

The ADO.NET Dataset is explicitly designed for data access independent of any data

source. As a result, it can be used with multiple and differing data sources used with XML dataor used to manage data local to the application. The Dataset contains a collection n of one or

more Data Table objects made up to rows and columns of data as well as primary key, foreign

key, constraint and relation information about the data in the Data Table objects.

BENEFITS OF ADO.NET

ADO.NET offers several advantages over previous versions of ADO and over other

data access components. These benefits fall into the following categories:

1. Interoperability

2. Maintainability

3. Programmability

4. Salability

MICROSOFT DATA ACCSS COMPONENTS (MDAC)

Microsoft Data Access Components (MDAC) is a collection of core files provided to

help applications by providing a means of accessing data. MDAC includes core files for Open

Database Connectivity (ODBC), ActiveX Data Objects (ADO), OLEDB, Network libraries and

client configuration tool for SQL Server. Depending on your data access strategy, you may need

to ensure that MDAC is installed on the client computers, the business servers, the Web servers

or the database servers. MDAC 2.6 or later is required by the .NET Framework and at least

MDAC 2.7 SP1 is recommended.
