PROFILE OF THE PROBLEM

The profile of the problem is that in previous time, counseling of any university

or colleges was held through paper work, that means for attending that

counseling we had to arrived on the place where university/colleges is located.

But now we can track student and perents contacts at the individual level.

So with the help of counseling system we can solve the problem through:-

Referral Tracking:- Track referrals to and from outside professionals as well asreferrals made internally within your organization. Simultaneously track multiple

referrals for individual students

Guideince Curriculum:-With the Deep Well Data Service (DWDS) ElementaryCounseling Data System, counselors are able to track their delivered curriculum

by date.

Counselor Time Sheet:- Counselors can track their time spent in the fourobjective areas of Individual Planning, System Support, Curriculum

Development, and Responsive Service. These categories can be added to or

modified to meet the needs of your project.

EXISTING SYSTEM

Introduction:-

Present system or Existing system of Counseling Management System working

manually or computerized in a building. Therefore all types works are maintain in

building. So maintain all the counseling procedure very difficult.

If we are reporting, then we need go to the University and get a form for reporting and fill

the form and submit in the queue conditions. Then verify there form by the university and

maintain the record in computer or register.

The system is mainly related to online counseling management system. Which is

developing an online web based application system, it is necessary to make a thorough

study of the existing system .There is no online Counseling Management System .The allthe information not maintains globally. Therefore to maintain all the information of

university is very difficult.

Limitations of the Existing System: -

The maintenance of various records and procedure of reporting are being done manually

by the counseling department. This leads to many drawbacks some of which are:

It is a time consuming process.

Proper arrangements should be made before and after the examination -which is both

money spending and time consuming.

As the number of students increases counseling process becomes more and more

difficult.

Not globally maintain the information


6/23

Evaluating of answer sheets also consumes heavy amount of time.

Difficult to management the all types of information of college or university.

Existing Software:-

There are a number of attributes of software that can serve as requirements. It is important

that required attributes by specified so that their achievement can be objectively verified.

The following items provide a partial list of examples.

The input system will allow for inputting numbers, operands, special symbols and letters of

the alphabets.

Problem Analysis

Product definition:-

C#.NET

C# language is intended to be a simple, modern, general-purpose, object-oriented

programming language.

The language, and implementations thereof, should provide support for software

engineering principles such as strong type checking, array bounds checking, detection of

attempts to use uninitialized variables, and automatic garbage collection. Software

robustness, durability,and programmer productivity are important.

The language is intended for use in developing software components suitable for

deployment in distributed environments.

Source code portability is very important, as is programmer portability, especially forthose programmers already familiar with C and C++.

Support for internationalization is very important.

C# is intended to be suitable for writing applications for both hosted and embedded

systems, ranging from the very large that use sophisticated operating systems, down to

the very small having dedicated functions.

Although C# applications are intended to be economical with regard to memory and

processing power requirements, the language was not intended to compete directly on

performance and size with C or assembly language.

FEATURES

There are no global variables or functions. All methods and members must be declared

within classes. Static members of public classes can substitute for global variables and

functions.

Local variables cannot shadow variables of the enclosing block, unlike C and C++.Variable shadowing is often considered confusing by C++ texts.

C# supports a strict Boolean datatype, bool. Statements that take conditions, such as

while and if, require an expression of a type that implements the true operator, such as the

boolean type. While C++ also has a boolean type, it can be freely converted to and from

integers, and expressions such as if(a) require only that a is convertible to bool, allowing


11/23

a to be an int, or a pointer. C# disallows this "integer meaning true or false" approach on

the grounds that forcing programmers to use expressions that return exactly bool can

prevent certain types of common programming mistakes in C or C++ such as if (a = b)

(use of assignment = instead of equality ==).

In C#, memory address pointers can only be used within blocks specifically marked asunsafe, and programs with unsafe code need appropriate permissions to run. Most object

access is done through safe object references, which always either point to a "live" object

or have the well-defined null value; it is impossible to obtain a reference to a "dead"

object , or to a random block of memory. An unsafe pointer can point to an instance of a

value-type, array, string, or a block of memory allocated on a stack.

Code that is not marked as unsafe can still store and manipulate pointers through the

system.

Managed memory cannot be explicitly freed; instead, it is automatically garbagecollected. Garbage collection addresses the problem of memory leaks by freeing the

programmer of responsibility for releasing memory which is no longer needed.

In addition to the try...catch construct to handle exception.

Multiple inheritance is not supported, although a class can implement any number of

interfaces. This was a design decision by the language's lead architect to avoid

complication and simplify architectural requirements throughout CLI.

C# is more type safe than C++. The only implicit conversions by default are those which

are considered safe, such as widening of integers. This is enforced at compile-time,

during JIT, and, in some cases, at runtime. There are no implicit conversions between

booleans and integers, nor between enumeration members and integers (except for literal

0, which can be implicitly converted to any enumerated type). Any user-defined

conversion must be explicitly marked as explicit or implicit, unlike C++ copy

constructors and conversion operators, which are both implicit by default. Starting with

version 4.0, C# supports a "dynamic" data type that enforces type checking at runtime

only.

Enumeration members are placed in their own scope.

C# provides properties as syntactic sugar for a common pattern in which a pair of

methods, accessor (getter) and mutator (setter) encapsulate operations on a single

attribute of a class.

Full type reflection and discovery is available.


12/23

C# currently (as of version 4.0) has 77 reserved words.

Checked exceptions are not present in C#. This has been a conscious decision based on

the issues of scalability and versionability.

Feasibility Analysis:-

Feasibility is the determination of whether or not a project is worth doing. The

process followed

in making this determination is called a feasibility study. In other words a

feasibility study is

carried out to select the best system that meets performance requirements.

Once it has been determined that a project is feasible, the analyst can go

ahead and prepare the

project specification which finalizes project requirements. Generally,

feasibility studies are

undertaken within tight time constraints and normally culminate in a written

and oral feasibility

The contents and recommendations of such a study will be used as a sound

basis for deciding

whether to proceed, postpone or cancel the project. Thus, since the

feasibility study may lead to the commitment of large resources, it becomes

necessary that it should be conducted competently and that no fundamental

errors of judgment are made.

In the conduct of the feasibility study, the analyst will usually consider seven

distinct, but interrelated types of feasibility. Three of them, which are used

hugely, are as follows:

Technical Feasibility


13/23

Operational Feasibility

Economic Feasibility

TECHNICAL FEASIBILITY

This is concerned with specifying equipment and software that will successfully satisfy

the user requirement. The technical needs of the system may vary considerably, but might

include:

The facility to produce outputs in a given time.

Response time under certain conditions.

Ability to process a certain volume of transaction at a particular

speed.

Facility to communicate data to distant location.

In examining technical feasibility, configuration of the system is given more importance

than the actual make of hardware.

The configuration should give the complete picture about the systems requirements:

How many workstations required? How these units are interconnected so that they could

operate and communicate smoothly. What speeds of input and output should be achieved

at particular quality of printing. This can be used as a basis for the tender document

against which dealers and manufacturers can later make their equipment bids. Specific

hardware and software products can then be evaluated keeping in view with the logical

needs. At the feasibility stage, it is desirable that two or three different configurations will be

pursued that satisfy the key technical requirements but which represent different levels of

ambition and cost. Investigation of these technical alternatives can be aided by approaching a

range of


14/23

suppliers for preliminary discussions. Out of all types of feasibility, technical feasibility

generally is the most difficult to determine.

ECONOMICAL FEASIBILITY

Economic analysis is the most frequently used technique for evaluating the effectiveness of a

proposed system. More commonly known as cost/benefit analysis; the procedure is to

determine the benefits and savings that are expected from a proposed system and compare

them with costs.

If benefits outweigh costs, a decision is taken to design and implement the system.

Otherwise, further justification or alternative in the proposed system will have to e made if it

is to have a chance of being approved. This is an ongoing effort that improves in accuracy at

each phase of the system life cycle.

OPERATIONAL FEASIBILITY

It is mainly related to human organizational and political aspects. The points to be considered

are:-

What changes will be brought with the system?

What organizational structures are disturbed?

What new skills will be required? Do the existing staff members havethese skills? If not, can they be trained in due course of time?

Generally project will not be rejected simply because of operational infeasibility but such

considerations are likely to critically affect the nature and scope of the eventual

recommendations. This feasibility study is carried out by a small group of people who are

familiar with information system techniques, who understand the parts of the business that

are relevant to the project and are skilled in system analysis and design process.

Project Plan

Planning and Scheduling is the detailed study of the various operations performed by a

system and their relationships within and outside of the system. During Planning and

Scheduling, data are collected on the available files, decision points, and transaction handled


15/23

by the present system. The planning and decision making is the good criteria to the

development of the project.

System analysis is simply uses several types of model and System Testing to their

development that is why the project get completed.

Software Requirement Analysis

Introduction:-


16/23

General Description:-

Specific Requirement Analysis:-

Information gathering is usually the first phase of the software development

project. The purpose of this phase is to identify and doucument the exact

requirements for the system. The users request identifies the need for a new

information system and on investigation re-defined the new information system

and on investigation re-defined the new problem to be based on MIS, which

supports management. The objective is to determine whether the request is

valid anf feasible before a recommendation is made to build a new or existing

manual system continues.

The major steps are:- Defining the user requirements, Studying the present

system to verify the problem, and defining the performance expected by the

candidate to use requirements.

System Design

Introduction: -

The objective of the system design is to deliver the requirements as specified in the feasibility

report. System design involves first logical design (logical design) and then physical construction

(detailed design) of the system. The logical design describes the structure and characteristics of

features, such as the outputs, inputs, files, databases, and procedures. The physical construction

produces actual program software, files, and a working system.

System design goes through two phases of development: -

1. Logical Design

2. Physical Design

Logical Design:-

We know that a data flow diagram shows the logical flow of a system and defines the boundaries

of the system. Logical design specifies the user need at a level of details that virtually determine

the information flow into and out of the system and the required data resources. Logical design

describes the inputs, outputs, database and procedures .All in a format that meets the users

requirements.

Physical Design:-

It provides the working system by defining the design specification that tells programmers

exactly what that candidate system must do. In short it can state that physical design is the

implementation of the logical design.

Physical system design consists of the following-

1) Design the physical system

i. Specify input, output media

ii. Design the database and specify backup procedures.

iii. Design physical information flow through the system and a

physical design walkthrough.

2) Plan system implementation

Detailed Design


19/23

There are some symbols that are used in the drawing of business process diagrams (data flow

diagrams). These are now explained, together with the rules that apply to them.

Flow diagrams in general are usually designed using simple symbols such as a rectangle, an oval

or a circle depicting a processes, data stored or an external entity, and arrows are generally used

to depict the data flow from one step to another.

A DFD usually comprises of four components. These four components can be represented by

four simple symbols. These symbols can be explained in detail as follows: External entities are

represented by squares; Processes (input-processing-output) are represented by rectangles with

rounded corners; Data Flows are represented by arrows; and finally, Data Stores are represented

by open-ended rectangles.

Data flow diagrams present the logical flow of information through a system in graphical or

pictorial form. Data flow diagrams have only four symbols, which makes useful for

communication between analysts and users. Data flow diagrams (DFDs) show the data used and

provided by processes within a system. DFDs make use of four basic symbols.

Create structured analysis, information flow, process-oriented, data-oriented, and data process

diagrams as well as data flowcharts.

External Entity

An external entity is a source or destination of a data flow which is outside the area of study.

Only those entities which originate or receive data are represented on a business process

diagram. The symbol used is an oval containing a meaningful and unique identifier.

Process

A process shows a transformation or manipulation of data flows within the system. The symbol

used is a rectangular box which contains 3 descriptive elements:

Firstly an identification number appears in the upper left hand corner. This is allocated arbitrarily

at the top level and serves as a unique reference.


20/23

Secondly, a location appears to the right of the identifier and describes where in the system the

process takes place. This may, for example, be a department or a piece of hardware. Finally, a

descriptive title is placed in the centre of the box. This should be a simple imperative sentence

with a specific verb, for example 'maintain customer records' or 'find driver'.

Data Flow

A data flow shows the flow of information from its source to its destination. A data flow is

represented by a line, with arrowheads showing the direction of flow. Information always flows

to or from a process and may be written, verbal or electronic. Each data flow may be referenced

by the processes or data stores at its head and tail, or by a description of its contents.

Data Store

A data store is a holding place for information within the system:

It is represented by an open ended narrow rectangle. Data stores may be long-term files such as

sales ledgers, or may be short-term accumulations: for example batches of documents that are

waiting to be processed. Each data store should be given a reference followed by an arbitrary

number.

Resource Flow

A resource flow shows the flow of any physical material from its source to its destination. For

this reason they are sometimes referred to as physical flows.

The physical material in question should be given a meaningful name. Resource flows are

usually restricted to early, high-level diagrams and are used when a description of the physical

flow of materials is considered to be important to help the analysis.

External Entities


21/23

It is normal for all the information represented within a system to have been obtained from,

and/or to be passed onto, an external source or recipient. These external entities may be

duplicated on a diagram, to avoid crossing data flow lines. Where they are duplicated a stripe is

drawn across the left hand corner, like this.

The addition of a lowercase letter to each entity on the diagram is a good way to uniquely

identify them.

Processes

When naming processes, avoid glossing over them, without really understanding their role.

Indications that this has been done are the use of vague terms in the descriptive title area - like

'process' or 'update'.

The most important thing to remember is that the description must be meaningful to whoever

will be using the diagram.

Data Flows

Double headed arrows can be used (to show two-way flows) on all but bottom level diagrams.

Furthermore, in common with most of the other symbols used, a data flow at a particular level of

a diagram may be decomposed to multiple data flows at lower levels.

Data Stores

Each store should be given a reference letter, followed by an arbitrary number. These reference

letters are allocated as follows:

'D' - indicates a permanent computer file

'M' - indicates a manual file

'T' - indicates a transient store, one that is deleted after processing.

In order to avoid complex flows, the same data store may be drawn several times on a diagram.

Multiple instances of the same data store are indicated by a double vertical bar on their left hand

edge.
