CLIENTS

ABSTRACT

Computerized Information System for Trade Tax enables a

state commercial taxation department to improve its services using IT. The software

covers various aspects of the working of the department.

The trade / commercial tax department is the organization that collects tax on the sale or

purchase of goods at a certain point of sale as well as purchase of goods throughout the

state. It may be divided into various zones, regions, circles, divisions or sectors to

facilitate better monitoring and control.

To enforce the commercial tax laws and to check tax evasion, there are several road

check-posts, railway check-posts, mobile squads and special investigation branches.



The ‘Computerized Information System for Trade Tax’

system has the following modules:

Dealer information system

Returns processing system

Dealer assessment system

Tax accounting system

Arrears recovery system

Software Requirement Specification

Purpose of this document:

Software Requirement Specification will assist the

potential users to determine if the software specified meets

their needs or how the software must be modified to meet

their needs.



And the complete descriptions of the functions which are

being carried out in the present system are to be performed by

the software specified in the SRS.

System Analysis:

Proposed System:

Information System for Trade Tax is specially designed for

organization to keep track of employee leave –tracking. This system aims to reduce the

paper-work to track-down employee leave with accuracy and minimal fuss, thus saving

time and money.

Our Trade Tax can retrieve the latest information for employees leave

application, leave cancellation, entitlement updating and leave approval which are

automated and user-friendly with the information displayed for preparing reports,

enquiries or updating relevant details.

By using this system the employee can apply, approve, cancel, postpone and

view leave records at their finger tips at anytime, anywhere.

Existing System:

In early days we maintain Information of an employee in the form of registers.

If we want to retrieve information regarding their leaves and dates we have to refer to

several sets of registers.

It was very time consuming and lengthy process .We needs to perform manual

upgrade whenever new features are added. It may lead to waste of time and money.

FEASIBILITY STUDY



Feasibility Study is a compressed capsule version of scope and objectives

is confirmed and corrected and any constraint imposed on the systems are identified.

Heuristics are searched as analyzed for feasibility. To yield a successful to the

organization that can be obtained through efficient feasibility study. These are a number

of feasibility studies to be conducted by the three equally important tests of feasibility

studies are:

Technical Feasibility

Operational Feasibility

Economical Feasibility

TECHNICAL FEASIBILITY:

Evaluating the technical feasibility is the trickiest part of a feasibility study. This

is because, at this point in time, not too many detailed design of the system, making it

difficult to access issues like performance, costs on (on account of the kind of technology

to be deployed) etc. A number of issues have to be considered while doing a technical

analysis.

1. Understand the different technologies involved in the proposed system

Before commencing the project, we have to be very clear about what are the

technologies that are required for the development of new system.

2. Find out whether the organization currently possesses the required technologies

Is the required technology available with the organization?

If so is the capacity sufficient?

For instance – “Will the current printer be able to handle the new reports and

forms required for the new system?”

OPERATIONAL FEASIBILITY:



Proposed projects are beneficial only if they can be turned into information

systems that will meet the organizations operating requirements. Simply stated, this test

of feasibility asks if the system will work when it is developed and installed. Are there

major barriers to Implementation? Here are questions that will help test the operational

feasibility of a project:

Is there sufficient support for the project from management from users? If the

current system is well liked and used to the extent that persons will not be able to

see reasons for change, there may be resistance.

Are the current business methods acceptable to the user? If they are not, users

may welcome a change that will bring about a more operational and useful

systems.

Have the user been involved in the planning and development of the project?

Early involvement reduces the chances of resistance to the system and in General

and increases the likelihood of successful project.

Since the proposed system was to help reduce the hardships encountered In the existing

manual system, the new system was considered to be operational feasible.

ECONOMIC FEASIBILITY:

Economic feasibility attempts 2 weigh the costs of developing and implementinga new system, against the benefits that would accrue from having the new system in

place. This feasibility study gives the top management the economic justification for the

new system.

A simple economic analysis which gives the actual comparison of costs and

benefits are much more meaningful in this case. In addition, this proves to be a useful

point of reference to compare actual costs as the project progresses. There could be

various types of intangible benefits on account of automation. These could include

increased customer satisfaction, improvement in product quality better decision making

timeliness of information, expediting activities, improved accuracy of operations, better

documentation and record keeping, faster retrieval of information, better employee

morale.

INCOME TAX:



The income from the other sources is one of the means of income and hence, included in

the Gross Total Income. The classical examples are Royalty, pension, remuneration-

received, winnings from lotteries, winnings from the crossword puzzles, income from

horse race, Income from undisclosed means and income other than the above. The set off

and carry forward of losses are reduced from the gross total income. This is availed as per

the sections of 69 to 71 of the Income Tax Act 1961. The set off and carry forward of

losses are availed subject to the conditions stipulated.

Income Tax Rates for the Assessment Year 2005-2006 Previous Year 2004-2005 are as follows

TOTAL INCOMERATE OF TAX

≤ Rs. 50,000Nil

Rs. 50,000 – Rs. 60,000 10 percentRs. 60,000 – Rs. 1,50,000 20 percentRs. 1,50,000 and above 30 percent

SALES TAX:

Is a consumption tax charged at the point of purchase for certain goods and

services. The tax is usually set as a percentage by the government charging the tax. There

is usually a list of exemptions. The tax can be included in the price (tax-inclusive) or added at the point of sale (tax-exclusive).

Most sales taxes are collected by the seller, who pays the tax over to the

government which charges the tax. The economic burden of the tax usually falls on the

purchaser, but in some circumstances may fall on the seller. Sales taxes are commonly



charged on sales of goods, but many sales taxes are also charged on sales of services.

Ideally, a sales tax is "fair", has a high compliance rate, is difficult to avoid, is charged

exactly once on any one item, and is simple to calculate and simple to collect.

Corporate Tax

A company has been defined as a juristic person having an independent and separate

legal entity from its shareholders. Income of the company is computed and assessed

separately in the hands of the company. however the income of the company which is

distributed to its shareholders as dividend is assessed in their individual hands. Such

distribution of income is not treated as an expenditure in the hands of company, the

income so distributed is an appropriation of the profits of the company.

VALUE ADDED TAX:

The system had been postponed many times, mainly because of opposition from

the powerful trading lobby. Ashim Dasgupta, who heads a panel overseeing the

implementation of VAT, said: "We are very happy to announce that a broad consensus

among states was arrived at the meeting to introduce VAT on April 1, 2005." The

Congress-led new left-leaning United Progressive Alliance (UPA) government has made

implementing VAT one of its key priorities.

An Overview of Servlets And JSP Technology

What is JDBC and why JDBC?

JDBC is a front-end tool for connecting to a server and is similar to ODBC

however, JDBC can connect only Java client and it uses ODBC for the connectivity.

JDBC is essentially a low level application programming interface. It is called a low level



API since any data manipulation, storage and retrieval has to be done by the program

itself. Some tools that Provide a higher level of abstraction is expected shortly.

The next question is why we need JDBC, once we have ODBC on hand. We can

use the ODBC to connect to all the databases and ODBC is a proven technology. Problem

for doing this is ODBC gives a ‘C’ language API, which uses pointer extensively, since

Java open JDBC to suit its needs.

Jdbc Driver Tipes

There are various types of driver, identified the sun such that each one has some

unique features and facilitates a connection to the database.

JDBC drivers fit into of four categories:

1. The JDBC-ODBC bridge provides JDBC access via most ODBC drivers. Note that

some ODBC binary code and in may cases database client code must be loaded on

each client machine that uses this diver so this kind of driver is most application on a

corporate network or for application server code written in Java in a 3-tier

architecture.

2. A native-API partly-Java driver converts JDBC calls into on the client API for Oracle

Sybase Informix DB2 or other DBMS. Note that, like the bridge driver this style of

driver requires that some binary code be loaded on each client machine.

3. A net-protocol all-Java driver translates JDBC calls into a DBMS-independent net

protocol which is then translated, to a DBMS protocol by a server. This net server

middle aware is able to connect its all Java client to many different databases. The

specific protocol used depends on the vendor. In general this is the most flexible

JDBC alternative. It is likely that all vendors of this solution will provide suitable for

intranet requirements for security, access through firewalls, etc. that the web imposes

several vendors are adding JDBC drivers to their existing database middle aware

products.

4. A native protocol driver

Jdbc Architecture

JDBC architecture is as follows

1. JDBC Driver Manager



2. JDBC Diver

3. JDBC-ODBC Bridge

4. Application

JDBC Driver Manager

Function of the driver manager is to find out available driver in the system and connect

the application to the appropriate database, whenever a connection is requested.

However, to help the driver manager identify different types of drivers, each driver

should be registered with the driver manager.

JDBC Driver:

Function of the JDBC driver is to accept the SQL calls from the application and convert

them into native calls to the database,. However, in this process it may take help from

some other drivers or even servers, which depends on the type of JDBC driver we are

using. It also is possible that the total functionally of the database server could be built

into the driver itself.

JDBC - ODBC Bridge :

Sun soft provides a special JDBC Driver called JDBC-ODBC bridge which can be used

to connect any existing database, that is ODBC complaint.

Servlet and JSP technology has become the technology of choice for developing

online stores, interactive Web applications, and other dynamic Web sites. Why? This

chapter gives a high-level overview of the reasons for its popularity. Later chapters

specific details on programming techniques.

A Servlet’s Job

Servlet are Java programs that run on applications servers. Acting as a middle layer

between requests coming from web browsers or other HTTP clients and databases or

applications on the HTTP server. Their job is to perform the following tasks.

Read the explicit data sent by the client.



The end user normally enters this data in an HTTP from on a web page. However the

data could also come from an applet or a custom HTTP client program. Chapter 4

discusses how servlet read this data.

Read the implicit HTTP request data sent by the browser.

The shows a single arrow going from the client to the web server (the layer where

servlets and JSP execute), but there are really two varieties of data: the explicit data that

the end user enters in a from and the behind-the –scenes HTTP information. Both

varieties are critical. The HTTP information includes cookies, information about media

types and compression schemes the browser understands and so forth it is discussed in

chapter 5.

Generate the results.

This process may require talking to a database, executing an RMI or EJB call, invoking a

web service, or computing the response directly your real data may be in a relational

database. Fine. But your database probably doesn’t speak HTTP or return results in

HTML, so the web browser can’t talk directly to the database. Even if it could, for

security reasons, you probably would not want it to.

The same argument applies to most other applications. You need the web middle layer to

extract the incoming data from the HTTP stream, talk to the application, and embed the

result inside a document.

Send the explicit data (i.e., the document )to the client.

This document can be sent in a variety of formats including text (HTML or XML), binary

(GIF images), or even a compressed format like zip that is layered on top of some other

underlying format. But, HTML is by far the most common format, so an important,

servlet / JSP task is to wrap the results inside of HTML.

Send the implicit HTTP response data.

The shows a single arrow going from the web middle layer (the servlet or JSP page) to

the client. But there are really two varieties of data sent: the document itself and the

behind-the –scenes HTTP information. Again both varieties are critical to effective



development. Sending HTTP response data involves telling the browser or other client

what type of document is being returned (e.g., HTTP), setting cookies and caching

parameters, and other such tasks.

Features of JSPJSP provides an attractive alternative to other dynamic scripting language by offering the

following features:

Platform independence:

The use of adds versatility to a web application by enabling its execution on any

computer.

Enhanced performance:

The compilation process in JSP produces faster results or output.Separation of logic from display:

The use of JSP permits the HTML-specific static content and a mixture of HTML, Java,

and JSP-specific dynamic content to be placed in separate fillies.

Ease of administration

The use of JSP eliminates the need for high-level technical expertise, thereby helping

web developers, content creators, and content managers to work together and develop

Java-based applications in less time and with less effort.

Ease of use:

All JSP applications run on major web server and operating systems, including Microsoft

IIS, Netscape enterprise server, I Planet web server, and apache web server. These

applications are available on Windows NT, windows 2000, and solaris7.

Competing Products across Platforms:

Competing products include active server pages (ASP), hypertext pre processor(PKP)

and Java script.

JSP versus ASP:

ASP is the immediate competing technology from Microsoft. The dynamic content of

JSP is written in Java, in contrast to that of ASP, which is written using an ASP-specific



language, such as VBScript. As a result, complex applications can use the power of Java

to result and embed Java components in JSP applications, second, JSP is portable to other

operating systems and servers in contrast to the allegiance of ASP to windows

NT/2000and IIS.

JSP versus PHP:

PHP is similar to ASP and JSP to a certain extent. PHP is a free, open-source, HTML-

embedded, server-side scripting language, with basic HTML knowledge, however, a

VBScript programmer can write ASP applications and a Java programmer can create JSP

applications, whereas PHP requires learning an entirely new language, second by virtue

if the power of Java, JSP has access to an extensive API for networking, database access,

and objects distribution.

JSP Objects & its Scopes

In JSP there are two types of objects.

Implicit objects

Explicit objects

Implicit objects are automatically created.

Explicit objects are created using actions.

Whenever a request has been made for a JSP PAGE, JSP page will create two types

of objects. They are:

1. Implicit objects

2. Explicit objects

Implicit objects are automatically created by the JSP web developers can use this

objects for their processing.

Explicit objects are created thought actions. Scripting code is used to create these

explicit objects. Every explicit object has some visible attribute. Scripting elements can

access the explicit objects thought scripting-level variables.

JSP defines several scopes for JSP objects.

Objects Scopes:

JSP defines several scopes for objects. Scopes are used to indicate the context in

which the bean should be made available.



Four types of scopes. They are:

1. Page

2. Request

3. Application

4. Session

While process the request, the JSP page can create and /or the some Java objects.

Scopes are used to indicate the context in which the dean should be made

available in JSP there are four scopes are available. They are:

Page:

It is the default scopes for all the Java objects. It is used to indicate that the objects are

only available on the current page. Once the response is sent back or the request is

forwarded somewhere else all the object reference, which has the page scope, will be

released object that contains

Page scope is stored in the page Content object of the current page.

Request:

The request scope is used to indicate that the objects are only available for the current

client request. If the request is forwarded to a resource in the same runtime, the Object is

still available. Once the request is processed, all the object reference, which has the

request scope, will be released. Objects that contain request scope will be released.

Object references that contain request scope are stored in the request Object.

Session:

The session scope indicates that the available to all pages during the life of the current

session. All references to the objects shall be released after the associated session ends.

References to objects with session scope are stored in the session objects associated with

the page activation.

Application:



The application scope indicates that it is available to all pages that share the same context

object references which contain the application scope will be released when the runtime

environment reclaims the servlet context objects references that contain the application

scope are stored are stored in the application objects associated with the page activation.

Directives And Actions:

JSP elements can be directives or actions. Directives elements provide global information

for the translation phase. Actions elements provide for the request-processing phase. New

action can be created from the tag extension mechanism.

JSP:

Elements can be directives or actions. Directive elements are used to provide global

information, which is not dependent for any specific received by the JSP page. For

example directive elements can be used to include the external file inside the JSP PAGE.

Action elements provide information, which is dependent on the details of the specific

request received by the JSP page.

Directive elements provide information for the compilation/translation phase.

Action can create some objects and may make available to the scripting element. Action

elements follow the syntax of XML elements.

JSP contains a tag extension mechanism that enables the addition of new actions.

Because of the mechanism JSP can b easily portable. Actions can be customized to

provide access to the attribute values and to their body. Custom action be nested and their

bodies can include scripting elements.

ODBC:

Two distinct ways to access ODBC data sources with DAO the Microsoft Jet database

engine DBC direct Microsoft jet provides a broad range of functionality. It handles many

of the details of establishing and managing connection, translating queries into a form

acceptable to the server, and managing returned data in some cases, if you want to bypass

the micro soft Jet database engine and use DAO to make calls directly to the ODBC

driver manager. This functionality is available through ODBC Direct.



The following steps offer a "quick start" to accessing ODBC data:

1. Use the ODBC data source manager in the windows control panel to setup your

ODBC data source and assign it a data

2. Source name (DSN)3. In your Visual Basic code, set an ODBC connect string that references the data

source. The connect string is used to establish a connection to the data source

4. Create a new table def object and set it’s connect string to the value specified in

step two.

5. Append the table to the table defs collection

6. Open a record-set object on the linked table. This record-set

7. Object contains data in your OBDC data source and you can manipulate it using the

properties and methods of a record-set object.





System Design

SOFTWARE ENGINEERING PARADIGM APPLIED- (RAD-MODEL)

The two design objectives continuously sought by developers are reliability and

maintenance.

Reliable System

There are two levels of reliability. The first is meeting the right requirements. A

careful and through systems study is needed to satisfy this aspect of reliability. The

second level of systems reliability involves the actual working delivered to the user. At

this level, the systems reliability is interwoven with software engineering and

development. There are three approaches to reliability.

1. Error avoidance: Prevents errors from occurring in software.

2. Error detection and correction: In this approach errors are recognized whenever they

are encountered and correcting the error by effect of error, of the system does not fail.

3. Error tolerance: In this approach errors are recognized whenever they occur, but

enable the system to keep running through degraded perform or by applying values

that instruct the system to continue process.

Maintenance:

While working it is the Key to reduce the need for maintenance, if possible to do

essential tasks.

1. More accurately defining user requirement during system development.

2. Assembling better systems documentation.

3. Using more effective methods for designing, processing, login and communicating

information with project team members.

4. Making better use of existing tools and techniques.



5. Managing system engineering process effectively.

Output Design

One of the most important factors of an information system for the user is the

output the system produces. Without the quality of the output, the entire system may

appear unnecessary that will make us avoid using it possibly causing it to fail. Designing

the output should process the in an organized well throughout the manner. The right

output must be developed while ensuring that each output element is designed so that

people will find the system easy to use effectively.

The term output applying to information produced by an information system

whether printed or displayed while designing the output we should identify the specific

output that is needed to information requirements select a method to present the

formation and create a document report or other formats that contains produced by the

system.

Types of output

Whether the output is formatted report or a simple listing of the contents of a file, acomputer process will produce the output.

• A Report

• A Document

• A Message

• Retrieval from a data store

• Transmission from a process or system activity

• Directly from an output sources

Layout Design

It is an arrangement of items on the output medium. The layouts are building a

mock up of the actual reports or document, as it will appear after the system is in



operation. The output layout has been designated to cover information. The outputs are

presented in the appendix.

Input design and control

Input specifications describe the manner in which data enter the system for

processing. Input design features will ensure the reliability of the systems and produce

results from accurate data, or thus can be

result in the production of erroneous information. The input design also determines

whenever the user can interact efficiently with this system.

Objectives of input design

Input design consists of developing specifications and procedures for data

preparation, the steps necessary to put transaction data into a usable from for processing

and data entry, the activity of data into the computer processing. The five objectives of

input design are:

• Controlling the amount of input

• Avoiding delay

• Avoiding error in data

• Avoiding extra steps

• Keeping the process simple

Controlling the amount of input

Data preparation and data entry operation depend on people, because labour costs

are high, the cost of preparing and entering data is also high. Reducing data requirement,

input requirement the speed of entire process from data capturing to processing will

increase to provide results for users.

Avoiding delay



The processing delay resulting from data preparation or data entry operations is

called bottlenecks. Avoiding bottlenecks should be one objective of input.

Avoiding errors

Through input validation we control the errors in the input data.

Avoiding extra steps

The designer should avoid the input design that cause extra steps in processing saving or

adding a single step in large number of transactions saves a lot of processing time or

takes more time to process.

Keeping process simple:

If controls are more people may feel difficult in using the systems. The best-designed

system fits the people who use it in a way that is comfortable for them.

Data dictionary

Admin-Table

The administrator is the person who is authorized to access all the

leaves and to scrutinize the leave0. So it is must to provide some mechanism for

accessing this account .So this table contains the details pertaining to the administrator

for his login. This table contains only one tuple which contains the details of the

administrator.

Design Document

• The entire system is projected with a physical diagram which

specifics the actual storage parameters that are physically necessary for any

database to be stored on to the disk. The overall systems existential idea is

derived from this diagram.

• The relation upon the system is structure through a conceptual ER-

Diagram, which not only specifics the existential entities but also thestandard relations through which the system exists and the cardinalities that

are necessary for the system state to continue.



DATA FLOW DIAGRAMS

Data flows are data structures in motion, while data stores are data structures.

Data flows are paths or ‘pipe lines’, along which data structures travel, where as the data

stores are place where data structures are kept until needed.

Data flows are data structures in motion, while data stores are data structures at

rest. Hence it is possible that the data flow and the data store would be made up of the

same data structure.

Data flow diagrams is a very handy tool for the system analyst because it gives

the analyst the overall picture of the system, it is a diagrammatic approach.

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.

A DFD does not show a sequence of steps. A DFD only shows what the different

process in a system is and what data flows between them.

The following are some DFD symbols used in the project

External entities

Data Flow Process

Process: A transaction of information that resides within

the bounds of the system to be module.

Data Store: A repository of data that is to be

stored for use by one or more processes may be as

simple as buffer of queue or as a relational

database.

Testing

Software testing is a critical element of software quality assurance and

represents the ultimate review of specification, design and coding. Testing is the

exposure of the system to trial input to see whether it produces correct output.



Testing Phases:

Software testing phases include the following:

• Test activities are determined and test data selected.

• The test is conducted and test results are compared with the

expected

Results.

There are various types of Testing:

Unit Testing:

Unit testing is essentially for the verification of the code produced duringthe coding phase and the goal is test the internal logic of the module/program. In the

Generic code project, the unit testing is done during coding phase of data entry

forms whether the functions are working properly or not. In this phase all the

drivers are tested they are rightly connected or not.

Integration Testing:

All the tested modules are combined into sub systems, which are then tested.

The goal is to see if the modules are properly integrated, and the emphasis being on

the testing interfaces between the modules. In the generic code integration testing is

done mainly on table creation module and insertion module.

System Testing:



It is mainly used if the software meets its requirements. The reference document

for this process is the requirement document. Acceptance Testing:

It is performed with realistic data of the client to demonstrate that the

software is working satisfactorily. In the Generic code project testing is done tocheck whether the Creation of tables and respected data entry was working

successfully or not.

Testing Methods:

Testing is a process of executing a program to find out errors. If testing is

conducted successfully, it will uncover all the errors in the software. Any testing

can be done basing on two ways:

White Box Testing:

It is a test case design method that uses the control structures of the

procedural design to derive test cases. using this testing a software Engineer can

derive the following test cases:

Exercise all the logical decisions on either true or false sides. Execute all loops at their

boundaries and within their operational boundaries. Exercise the internal data structures to assure

their validity.

Black Box Testing:

It is a test case design method used on the functional requirements of the

software. It will help a software engineer to derive sets of input conditions that will

exercise all the functional requirements of the program. Black Box testing attempts

to find errors in the following categories:

Incorrect or missing functions

Interface errors

Errors in data structures

Performance errors

Initialization and termination errors

By black box testing we derive a set of test cases that satisfy the following criteria:



Test cases that reduce by a count that is greater than one, the number of additional

test cases that must be designed to achieve reasonable testing.

Test cases that tell us something about the presence or absence of classes of errors

rather than errors associated only with a specific test at hand.

TEST APPROACH:

Testing can be done in two ways:

• Bottom up approach

• Top down approach

Bottom up approach:

Testing can be performed starting from smallest and lowest level modules and

proceeding one at a time. For each module in bottom up testing a short program executes

the module and provides the needed data so that the module is asked to perform the way

it will when embedded with in the larger system. When bottom level modules are tested

attention turns to those on the next level that use the lower level ones they are tested

individually and then linked with the previously examined lower level modules.

Top down approach: Following is a template for the RS document. Some

example requirements are entered in to it to show how to use the template. Make sure that

you enter even the smallest/most trivial requirements also. That would help in validating

the system during testing.

This type of testing starts from upper level modules. Since the detailed activities

usually performed in the lower level routines are not provided stubs are written. A stub is

a module shell called by upper level module and that when reached properly will return a

message to the calling module indicating that proper interaction occurred. No attempt is

made to verify the correctness of the lower level module.

Test-Plan (TP)

The test-plan is basically a list of testcases that need to be run on the system.

Some of the testcases can be run independently for some components (report generation

from the database, for example, can be tested independently) and some of the testcases

require the whole system to be ready for their execution. It is better to test each

component as and when it is ready before integrating the components.

It is important to note that the testcases cover all the aspects of the system (ie, all

the requirements stated in the RS document).

CONCLUSION



The Information System For trade Tax is an intranet based application that

can be accessed throughout the organization or a specified group or department. This

system can be used to automate the work flow of leave applications and their

approvals. There are features like e-mail notifications, cancellation of leave

,automatic approval of leave, report generators etc in this system. This system is

important to any kind of an organization .

SCOPE FOR EXPANSION
