       SYNOPSIS

The science and technology has improved to a very great height. The world is

going on a fast track. Time plays a prominent role in our day-to-day life.

The project titled “SOFTWARE FOR DTH DISTRIBUTOR” has been

exclusively developed for all direct DTH distributors. The main objectives of the

system are to maintain all the master tables of Proof types, Box Models, Area Details and

Dealer details.

The system deals all the account information very efficiently and accurately. This

system gives the information about the Employee details. The system is useful for the

effective utilization and gives related information to the organization people. It gives the

report of various details and result for the distributors. The system reduces most of

manual work.

2. SYSTEM ANALYSIS

System study is the process of gathering and interpreting facts, diagnosing

problems of the system. System study begins with the determination of the system

requirements, which can be done by the study of an existing system.

The next step is to determine what the proposed system is suppose to do. The final

step is to determine the need for computerization, Hardware and Software configuration

should be evaluated to determine the suitable platform for the system.

2.1 Feasibility Study

As the feasibility study is very important for software development. The system

will be feasible, only if it is feasible in all aspects. The feasibility study tries to find out

answer for the following questions.

Is the system is really needed?

Is the resource management system can do something helpful to the

employees and students?

Is the system development project is achievable with the available money,

time and manpower?

The system proposed is tested whether it is feasible, by conducting the following

feasibility study.

Operational feasibility

Technical feasibility

Economical feasibility

9

Operational Feasibility

Once the system is developed completely, it must be put into use. A reasonable

acceptance from the user side is necessary for the success of the system. Since user

welcomes the expert systems, the system is found to be operationally feasible.

Technical Feasibility

The hardware and software requirements of the proposed system are already made

available for use. If new technology is required, what is the likelihood that it can be

developed? Thus the system is technically feasible.

Financial Feasibility

The existing system is enough for implementing the system and also for further

software developments in terms of labour and manpower, it is adequate and no extra

personal is required.

2.2 Existing System

The existing system is considered as manual system. In manual system all entries,

the transactions, calculations, report preparations, etc., are carried manually. Every end

user must have the knowledge about the transactions.

While entering, the user may commit some mistakes, which may leads to the

drastic errors. Every transaction entered clearly. The manual errors may occur due to

wrong calculations, transactions, report preparations, etc. So the reports prepared may

contain some errors. Sometimes a rough work is needed. Which is a time consuming

process.

10

Disadvantages of existing system

Being a clerical procedure the existing system encounters the following problems:

The entries are done manually. It may take more time when more entries

are been made.

In calculations, mistakes may occur.

Calculation are correct, but its entry may be wrong.

The cost for maintenance of the record and more over the employment

charges are alos higher.

Less security and less reliable.

2.3 Proposed System

Most of the pitfalls are discovered in the existing system and they are thoroughly

eliminated in the proposed system. The aim of proposed system is to computerize the

activities like data entry, calculations, reports etc. By integrating the above functions into

a single system we can maintain the entries, display, calculation, reports and modification

of records very effectively and quickly.

The main functions which are concentrated in this system are

No record should be redundant.

No manual calculations required.

Records are maintained perfectly.

Reports are produced in a neat format.

11

Better security to the data.

The proposed system is developed using Visual Basic.Net 2005 as front-end, SQL

Server 2000 as back-end. It is reliable, easy understandable and a user-friendly software.

A person with little bit of computer knowledge can operate this software. The software is

designed in a similar way we do a manual entry.

The major characteristics of the system are:

Capturing data through forms.

Avoiding data redundancy and thereby saving time trough reduction of

errors.

User friendly and reliable.

12

SYSTEM DESIGN

System design is the process of planning a new system or to replace components

of an existing system. System design involves logical design and then physical design of

the system.

Logical Design

It contains the specification for the new system. It describes the features, the

outputs, and the inputs.

Logical Data Flow Diagram

This diagram is completed using only three symbols and notations:

Data Flow

Data moves in a specific direction from an object to a destination.

Source

External source of data, which may be people, programmer, organization or other

entities that interact with the system.

Process

People, procedure or devices that use or produce data.

Data Store

3.4 About the Software

Introduction to Visual Studio .Net

The Microsoft .NET frame work provides platform for the development of

applications for both the desktop and the internet. The .NET framework allows us to

develop internet applications with an ease that was never provided before. To develop

Internet Applications, the .NET framework is equipped with ASP.NET. It is a powerful

programming framework for the development of enterprise class Web applications.

Visual Studio .NET is the first release of the products based on the .NET

framework. It includes Visual Basic; Visual C++ and C#.VS.NET provides a common

Integrated development environment for all languages. Therefore, developers always

work in a consistent environment irrespective of the language they use.

Microsoft introduced the .NET framework with a vision for developers to create

globally distributed software with internet functionality and interoperability. The .NET

framework includes multiple languages, class libraries, an a common execution platform.

In addition, the .NET framework includes protocols that allow developers to integrate

software over the internet and the .NET enterprise servers such as SQL Server 2000,

Commerce Server 2000 and BizTalk Server. Thus the .NET framework provides the

richest built-in functionality for software integration ever provided by any platform. Also

with the .NET framework, developing the internet applications is as easy as developing

desktop applications.

5.2 Introduction To SQL-Server

IBM Invented a computer language back in the 1970’s designed specifically for

database Queries called SEQUEL which stood for Structured English Query language.

20

Over time the language has been added to, So that it is not just a language for Queries but

can also be used to build databases and manage security of the databases engine. IBM

released SEQUEL in to public domain. Where it was known as SQL-SERVER

SQL-SERVER is used to communicate with the relational database which is in

turn a set of related information stored in the form of table.

It is a non-procedural language because it processes set of records rather than just

one data at a time and also provides automatic navigation of data. Here one can

manipulate a set of rows than one at a time. It commands allow a set row as input and set

of rows as output.

It is also utilized as the communication language with the database among the

database users at database administrator. System administrators, security administrators

and application programmers. It provides commands for a variety of tasks including

1. Querying data

2. Inserting, updating and deleting rows in an object

3. Creating, replacing, altering and dropping objects

4. Controlling access to the database and its objects guaranteeing database

consistency and integrity

The SQL language is subdivided according to their function as follows.

1. Data Definition Language (DDL).

2. Data Manipulation Language (DML).

3. Transaction Control Language (TCL).

21

SQL SERVER AND THE CLIENT/SERVER MODEL

Microsoft’s SQL server is a Client/Server database engine, so it is important for

you to understand the Client/Server model.

A client/Server application can be defined as one that is split in to two parts: one

part runs on a Server, and the other Part runs on Workstations. The server side of the

application provides security, fault tolerance, performance, concurrency, and reliable

backups. The client side provides the user interface and can contain empty reports,

Queries, and forms. The ideas is to have the best of both works by taking advantage of

both and pairing them together.

SQL server is the server part of the education; various clients to choose from can

connect to SQL Server, including the Utilities that come with SQL server such as the

SQL Server, such as the SQL server Query Analyzer.

SQL server provides the following advantages for both clients and servers.

Client advantages

Easy to use

Supports multiple hardware platforms

Supports multiple software applications

Familiar to the user

Server advantages

Reliable

Concurrent

Sophisticated locking

Fault tolerant

22

High-Performance hardware

Centralized control

In Client/Server computing, when a Query is ran, the server searches the database and

sends only the rows that are a match to the client. This not only saves bandwidth, but it

can be faster than having the workstations perform the query. As the server is a powerful

enough machine.

4.2 Software Testing

Testing is an activity that ensures whether a correct system is built or not. It is

carried out not only after the development phase is completed, but also is parallel with all

stages of development. It is an important stage in System Development Life Cycle. The

test case is a set of data that a system will process as normal input. As the philosophy

behind testing is to find errors if exists and to check whether the system will process the

data correctly.

Software testing is an important element of software quality assurance and

represents the ultimate review of specification, design and coding. The increasing

visibility of software as a system element and the costs associated with a software failure

are motivating forces for well planned thorough testing.

Testing should not be done as a single phase; it should be integrated with all

phases of the software development life cycle. Testing seems to be negative but it is the

process, which brings out the creativity of the software professional. Test data or test case

is to be designed before testing begins. Testing can be performed at different stages.

Based on this testing is classified into various types.

Unit Testing.

Interface Testing.

Black Box Testing.

White Box Testing.

Integration Testing.

System Testing.

32

Unit Testing :

Testing should be started as early as possible in the software development

process. Unit testing involves testing individual modules or units for errors. As each unit

is developed it is tested for errors by the test team which consists of members not in the

development team. The project leader just explains the requirements and functionality of

the module and hands over the module to the testers. They validate the module against

the requirements gathered. Any errors found are reported to the project team for

correction.

Interface Testing:

After developing the system, it has to be tested by end user because he is the

person who is going to use the system, is called interface testing. The ultimate aim of the

system is to design a completely user friendly software so the user found it to be easy.

Black-Box Testing

Black-Box tasting attempts to find error in the following categories.

o Incorrect or missing functions

o Interface errors

o Errors in data structures or external data base access

o Performance errors

o Initialization and termination errors

Using this method, the functional validity is tested, good test cases are found,

they are verified. The system sensitivity is checked for certain input values. The

tolerance of data rates and data volume of the system is verified.

33

White-Box Testing:

This is a test case design method that uses the control structure of the procedural

design to derive test cases. Using it, the software engineer can derive test cases that,

o All independent paths within a module have been checked.

o Exercise all logical decision on their true and false sides

o Exercise all loops at their boundaries and within operational bounds

o Exercise internal data structures to assure their validity.

Integration Testing:

The need for the integrated test is to find the overall system performance. Once

each module has been tested individually it has to be integrated into a single system.

While testing the whole application we can expect many errors because there should be

proper interaction between modules. So integrated testing has been performed

successfully after uniting all modules.

System Testing:

System testing is designed to uncover errors that was not found in earlier tests.

Here the entire system is validated from performance. This includes forced system

failure, providing heavy workload to test the system performance in unexpected

conditions. The total system is also tested for recovery and fallback after various major

failures.

34

13. CONCLUSION

The Project Entitled “SOFTWARE FOR DTH DISTRIBUTOR”

used to maintain the customer, manufacture, category, product, sales

and product details. There are more number of verification and

validations done by this system. The system responds positively to the

test done in this system.

The System is a user friendly one. The end user need not have

the full computer knowledge. The user can handle the system very

easily and the changes can be made very easily. The entire system

was developed with full documentation within in the stipulated time

period with minimum usage of available resources.
