2.1 PROJECT PROFILE2.1 PROJECT PROFILE

Today almost every organization or educational institute has its own payroll system to support its work within the organization.

The organizations need to maintain the record all the employee, so that no one can misuse the resources allocated to the users in the organization.

Our payroll record system is such a system that can be used to solve this purpose.

This system can be used in organizations to maintain the work of its employees, in educational institutes, organisation to maintain the record of all employee.

A. OBJECTIVE

Our objective is to learn the concept behind the payroll system, and to learn new technologies like Swings programming by implementing this concept practically.

The ultimate aim is achieved through-

1. Understanding and analyzing the problem statement.

2. Identify the input and output requirements of the system.

3. Designing a user-friendly interface to interact with the system Implementing and deploying the system.

4. Preparing a well-organized documentation of the project to understand the system and it’s working.

B. PURPOSE


4

Almost every organization or educational institute has its own Staff to support its work within the organization. The organizations need to work and every employee get perfect salary. so that no one can misuse the resources in the organization. We need to develop such a payroll system that can perform following tasks-

Can enter the new employee entry.

Can see the exit employee detail.

Can maintain the exit employee salary record.

Can make a new month salary.

That system should support organizations to maintain the salary record of its employees

3. SYSTEM ANALYSIS

3.1 PRESENT SYSTEM & ITS LIMITATION


6

It will work in one portal.

We have now a great solution for payroll system in our hand, but still it have some limitations.

We can run this system and maintain all pay record of employee and employee can’t open because the region of user name password

The other limitation of the system is that the client should have Java installed on it otherwise the system will not work.

Further Enhancements and Suggestions, we can maintain the record up ten year past & ten year future.

We will try to resolve this limitation in our future work.

3.2 NEED OF THE SYSTEM

The system will be used for following purpose in any organization-

To maintain the payroll system of the employee.

To restrict empolyee from performing illegal task and misuse resources.

To get the information regarding the employee performance.

To communicate with the employee for giving instructions or other reasons.

6. TECHNICAL SPECIFICATION

6.1 TECHNOLOGY UESD

We will implement our project in JAVA, one of the most powerful

languages.

Java Development Kit

When the java programming language was introduced in 1995,

the only development tool available was the JDK from sun. This

set of command line tools makes it possible to write, compile and

debug JAVA programs. However, the JDK is the far cry from

integrated development environment such as Visual Basic and

Borland c++. An integrated development environment (IDE) is

software that combines several development tools into a single,

cohesive package. The assortment usually includes a source code

editor, compiler debugger and other utilities. These tools work

together the development process; most packages are highly

visual and rely on windows, drag and drop, and other graphical

elements. The goal is to make software design faster, more

efficient, and easier to debug.


17

Characteristics of Java

JAVA is object oriented

Object oriented programming is a power full way of organizing

and developing software. Object oriented programming uses a

set of components called objects. These objects exist

independently of each other and communicate with each

other. That’s why object oriented program are more adoptable

and more bug proof.

JAVA is small and simple

The most complex parts of c++ were excluded from java, such

as pointers and memory management. These elements are

complicated to use and are thus easy to se incorrectly.

JAVA is safe

Another thing essential to java’s success is that it is safe. Java

provides security and several different levels. Before a java

program is run, a verifier check each by code to make sure

nothing suspicious is going on.

JAVA is platform independent

Platform independence is another way of saying that java is

architectural neutral. The basically means that java programs

don’t care what system they are running on.

JAVA is architectural neutral


18

The JAVA designers made several hard decisions in the java

languages and JVM is an attempt to alter the situation

programs not running on the same machine after few days.

Their goal was “Write once; run anywhere, anytime, forever”.

JAVA is Distributed

Java is designed for the distributed environment of Internet

because it handles TCP/IP protocols. The feature of inter-

address-space messaging is done with the help of package

Remote Method Invocation (RMI). This feature brings an

unparalleled level of instructions to the client/server

programming.

JAVA is dynamic

Java programs carry with them substantial amounts of run

time type information that is use to verify and resolve

accesses to objects at run time. This is crucial to the

robustness to the applet environment.


19

6.2 TECHNICAL INFORMATION

Swings

Swing is set of classes that provide more powerful and flexible functionality than is possible with the standard AWT components. In addition to the familiar components, such as buttons, check boxes, and labels, Swings supplies several exciting additions including tabbed panes, scroll panes, trees, and a button may have both image and text string associated with it. Also the image can be changed as the state of the button changes.

Swing is built upon the foundation of the AWT. Unlike AWT components, Swing component are not implemented by platform specific code. Instead they are written entirely in Java and therefore are platform independent. The term lightweight is used to describe such elements.

The class Swing Utilities, which provides methods that, facilitates the use of Swing. The Swing related classes are contained in javax.swing.tree and its sub packages, such as javax.swing.tree.

Swing is a large system, and it has many features. Swing provides toolbar, tool tips, and progress bars. Also swing component can provide a pluggable look and feel, which means that it is easy to substitute another appearance and behavior for an element. This can be also done dynamically. We may design our own look and feel. Because of the power of swing, it has become the approach of first choice by many programmers for creating GUIs

SQL SERVER

DATABASE

A database management, or DBMS, gives the user access to

their data and helps them transform the data into information.

Such database management systems include dBase, paradox,

IMS, SQL Server and SQL Server. These systems allow users to

create, update and extract information from their database.

A database is a structured collection of data. Data refers to

the characteristics of people, things and events. SQL Server

stores each data item in its own fields. In SQL Server, the fields

relating to a particular person, thing or event are bundled

together to form a single complete unit of data, called a record (it

can also be referred to as raw or an occurrence). Each record is

made up of a number of fields. No two fields in a record can have

the same field name.

During an SQL Server Database design project, the analysis

of your business needs identifies all the fields or attributes of

interest. If your business needs change over time, you define

any additional fields or change the definition of existing fields.

SQL Server Tables


21

SQL Server stores records relating to each other in a table.

Different tables are created for the various groups of information.

Related tables are grouped together to form a database.

Primary Key

Every table in SQL Server has a field or a combination of

fields that uniquely identifies each record in the table. The

Unique identifier is called the Primary Key, or simply the Key.

The primary key provides the means to distinguish one record

from all other in a table. It allows the user and the database

system to identify, locate and refer to one particular record in the

database.

Relational Database

Sometimes all the information of interest to a business

operation can be stored in one table. SQL Server makes it very

easy to link the data in multiple tables. Matching an employee to

the department in which they work is one example. This is what

makes SQL Server a relational database management system, or

RDBMS. It stores data in two or more tables and enables you to

define relationships between the table and enables you to define

relationships between the tables.

Foreign Key


22

When a field is one table matches the primary key of

another field is referred to as a foreign key. A foreign key is a

field or a group of fields in one table whose values match those of

the primary key of another table.

Referential Integrity

Not only does SQL Server allow you to link multiple tables, it

also maintains consistency between them. Ensuring that the

data among related tables is correctly matched is referred to as

maintaining referential integrity.

Data Abstraction

A major purpose of a database system is to provide users

with an abstract view of the data. This system hides certain

details of how the data is stored and maintained. Data

abstraction is divided into three levels.

Physical level: This is the lowest level of abstraction at which

one describes how the data are actually stored.

Conceptual Level: At this level of database abstraction all the

attributed and what data are actually stored is described and

entries and relationship among them.

View level: This is the highest level of abstraction at which one

describes only part of the database.

Advantages of RDBMS


23

Redundancy can be avoided

Inconsistency can be eliminated

Data can be Shared

Standards can be enforced

Security restrictions ca be applied

Integrity can be maintained

Conflicting requirements can be balanced

Data independence can be achieved.

Disadvantages of DBMS

A significant disadvantage of the DBMS system is cost. In

addition to the cost of purchasing of developing the software, the

hardware has to be upgraded to allow for the extensive programs

and the workspace required for their execution and storage.

While centralization reduces duplication, the lack of duplication

requires that the database be adequately backed up so that in

case of failure the data can be recovered.

FEATURES OF SQL SERVER (RDBMS)


24

SQL SERVER is one of the leading database management

systems (DBMS) because it is the only Database that meets the

uncompromising requirements of today’s most demanding

information systems. From complex decision support systems

(DSS) to the most rigorous online transaction processing (OLTP)

application, even application that require simultaneous DSS and

OLTP access to the same critical data, SQL Server leads the

industry in both performance and capability

SQL SERVER is a truly portable, distributed, and open DBMS that

delivers unmatched performance, continuous operation and

support for every database.

SQL SERVER RDBMS is high performance fault tolerant DBMS

which is specially designed for online transactions processing and

for handling large database application.

SQL SERVER with transactions processing option offers two

features which contribute to very high level of transaction

processing throughput, which are

The row level lock manager

Enterprise wide Data Sharing


25

The unrivaled portability and connectivity of the SQL

SERVER DBMS enables all the systems in the organization to be

linked into a singular, integrated computing resource.

Portability

SQL SERVER is fully portable to more than 80 distinct

hardware and operating systems platforms, including UNIX,

MSDOS, OS/2, Macintosh and dozens of proprietary platforms.

This portability gives complete freedom to choose the database

sever platform that meets the system requirements.

Open Systems

SQL SERVER offers a leading implementation of industry –

standard SQL. SQL Server’s open architecture integrates SQL

SERVER and non –SQL SERVER DBMS with industries most

comprehensive collection of tools, application, and third party

software products SQL Server’s Open architecture provides

transparent access to data from other relational database and

even non-relational database.

Distributed Data Sharing


26

SQL Server’s networking and distributed database

capabilities to access data stored on remote server with the same

ease as if the information was stored on a single local computer.

A single SQL statement can access data at multiple sites. You can

store data where system requirements such as performance,

security or availability dictate.

Unmatched Performance

The most advanced architecture in the industry allows the

SQL SERVER DBMS to deliver unmatched performance.

Sophisticated Concurrency Control

Real World applications demand access to critical data.

With most database Systems application becomes “contention

bound” – which performance is limited not by the CPU power or

by disk I/O, but user waiting on one another for data access . SQL

Server employs full, unrestricted row-level locking and contention

free queries to minimize and in many cases entirely eliminates

contention wait times.

No I/O Bottlenecks


27

SQL Server’s fast commit groups commit and deferred write

technologies dramatically reduce disk I/O bottlenecks. While

some database write whole data block to disk at commit time,

SQL Server commits transactions with at most sequential log file

on disk at commit time, On high throughput systems, one

sequential writes typically group commit multiple transactions.

Data read by the transaction remains as shared memory so that

other transactions may access that data without reading it again

from disk. Since fast commits write all data necessary to the

recovery to the log file, modified blocks are written back to the

database independently of the transaction commit, when written

from memory to disk.


28

7. TESTING

Software testing is a critical element of software quality

assurance and represents the ultimate review of specification,

design and code generation.

Once source code has been generated, software must be tested

to uncover as many errors as possible before delivery to the

customer.

Our goal is to design a series of test cases that have a high

likelihood of finding errors. That’s where software testing

techniques come into the picture.

These techniques provide systematic guidance for designing tests

that exercise the internal logic of software components and

exercise the input and output domains of the program to uncover

errors in program function, behavior and performance.

For this testing techniques are used. These techniques provide

systematic guidance for designing tests that -

(1) Exercise the internal logic of software components and

(2) Exercise the input and output domains of the program to

uncover errors in program function, behavior and performance.


29

Testing objective

A number of rules that can serve as testing objectives are: -

1. Testing is a process of executing a program with the intent

of finding an error.

2. A good test case is one that a high probability of finding an

as-yet-undiscovered error.

3. A successful test is one that uncovers an as-yet-

undiscovered error.

Testing Methods

All tests should be traceable back to some requirements of the

customer.

The test should be planned before testing begins and as soon as

requirements model is complete.

The earlier test planned and executed focus on individual

components. As testing progresses, focus shifts in an attempt to

find errors in integrated cluster of components and ultimately in

entire system. Exhaustive testing is not possible because it is

impossible to execute every combination of paths during testing.

White Box Testing


30

It is also called Glass Box Testing. It is a test case design method that uses control structure of the procedural design to derive test cases. Using White Box Testing methods, the software engineer can derive test cases that guarantee that all independent paths have been exercised at least once. Exercised all routes at their boundaries and within their operational bounds. Exercised all logical decision on their true and false sides. Exercised internal data structure to assure their validity.

Black Box Testing

Black Box Testing focuses on the functional requirements of

the software. That is, Black Box Testing enables the

software engineer to derive sets of input conditions that will

fully exercise all functional requirements for a program.

Black Box Testing is not an alternative to White Box Testing.

Rather, it is a complementary that is likely to uncover a

different class of errors than White Box Testing. Black Box

Testing attempts to find errors on the following categories –

1. In-correct or missing functions.

2. Interface errors.

3. Errors in data structures or external database access.

4. Performance errors.

5. Initialization and termination errors.

6. System Analysis

Process Model Used


31

Description

Rapid Application Development is incremental software

development process model that emphasizes an extremely

short development cycle. The RAD model is a “high-speed”

adaptation of linear sequential model in which rapid

development is achieved by using component-based –

construction.

Used primarily for information systems applications, the

RAD approach encompasses the following phases:

Business Modeling- The information flow among business

functions is modeled in a way that answers the following

questions: What information drives the business process?

What information is generated? Who generates it? Where

does the information go? Who processes it?

Data Modeling- The information defined as part the business

modeling phase refined into a set of data objects that

are needed to support the business. The characteristics

of each object are identified and the relationship between

these objects defined.

Process modeling- The data objects defined in the data-

modeling phase is transformed to achieve the

information flow necessary to implement a business


32

function. Processing descriptions are created for adding,

modifying, deleting, or retrieving a data object.

Application generation- RAD assumes the use of fourth

generation techniques. Rather than creating software

using conventional third generation programming

languages the RAD process works to reuse existing program

components or create reusable components. In all cases,

automated tools are used to facilitate construction of the

software.

Testing and turnover-

Since RAD process emphasizes reuse many of the program

components have already been tested. This reduces overall

testing time. However new components must be tested and

all interface must be fully exercised.

9. LIMITATIONS


38

We have now a great solution for network monitoring in our hand, but still it have some limitations.

We can’t run this system in hidden mode i.e. client will know that he is being monitored.

The other limitation of the system is that the client should have Java installed on it otherwise the system will not work.

10. FUTURE ENHANCEMENT


39

Can be developed as a web based application. Many more

modules can be added such as promotion. It can also include

information about employee salary incensement.

11. CONCLUSION


40

This system is just an introduction to the world of software for employee payroll information system where every record matter a lot and can make big difference can effect the employee carrier so this system provides the facility to automat employee data processing making the system error free and easy to access.
