1. INTRODUCTION

DataBase is a collection of information that is used forseveralpurposes and DataBase Management system is an applicationSoftware,that has some specific programs to access the datas in thedatabase.Data bases help the users to create a large amount of information’s andstored it in a file system or in a memory chip, In normal casesclerks have a lot of works to record, search, edit the details

of a employee at the firm, it wastes a lot of times andtheir may be errors in the data , Here we introduce the"EMPLOYEE MANAGEMENT SYSTEM". By using this software we canovercome all most all such problems like data redundancy,inconsistancy. And it also helps to impliment standards

SYSTEM STUDY

The system study is indented with the study of theexisting system; that is about the current Data base system, the

working of the system , the concerned modules, and requirements

etc . It also deals with the benefits and disadvantages of the

system . We must thoroughly understand the old system and

determine how computers can best be used to make its operations

more effective.

Before development of any project can be pursued, a

system study is conducted to learn the details of the current

business situation . Information gathered through the study , forms

the basis for creating alternative design strategies . Management

selects the strategy to pursue.

2.1 Existing System

The existing system is studied to know the extent of

computerization required. Therefore , a detailed analysis of the

existing system should be conducted . For this purpose , system

should be broken down into various subsystems and these

subsystems were analyzed closely to identify the problem areas.

As we studied the existing system, it was found that

there is a File Management system which gives the facility for

accessing the employee details . In a File Management all works

5

Project Report




are done manually. The main problem of the manual operation is,

it is time consuming and error prone than the computerized system.

There exists wastage of data retrieved time as in the case of search

and further processing. There was no efficient system to manipulate

the existing records.

The problem I observe in this area is that the

user has to do all the operations manually , by searching and

analyzing large amount of data, a miss-spelled digit or character may

create many hours of extra work and complicated correction

procedure. Necessary data validation checks are included to avoid

mistakes

2.2 PROPOSED SYSTEM

The existing system leads to many errors like dataredundancy, data inconsistency, and also much more paper worksthat waste very valuable time and money. We collect a lot of information from different current tools and it’s advantages.

Keeping this in mind we decided to develop asoftware and named as “EMPLOYEE MANAGEMENT SYSTEM” whichis very userfriendly and helps to make research a real chore. Thiscomputerization improves efficiency of office work, and also helps tokeep data too many years without damage and can be recollectedas and when needed without much time

The Proposed system solves problems related to dataaccessing problems, because it help the user to add details of theemployee to the firm database easily ,improving data recoveryspeed, easy searching and also provide editing of data’s in thedatabase

ANALYSIS

Project Report




4 .1 Feasibility Analysis The main objective of feasibility study is to test the

technical, social and economic feasibility of developing a system.

This is done before developing a system . This is done by

investigating the existing system in the area under investigation and

generating ideas about the new system.

4.1.1 Economic and Technical Feasibility The system must be evaluated from the technical view

point first. The assessment of this feasibility must be based on an

outline design of the system requirement in terms of input, output,

programs, procedure and staff. Having identified the outline of the

system, the investigation must go on to suggest the type of

equipment, required method of developing the system, and the method

of running the system

This developing system must be justified by cost andbenefit criteria to ensure that effort is concentrated on project which

will give best return at the earliest . One of the factors which affect

the development of a new system is the cost it would require. Since

the system is developed as a part of our study , there is no

manual cost to be spent for the proposed system.

4.1.2 Social and Behavioral Feasibility

10

Project Report




Proposed project would be beneficial only if they can

be turned into information system that’ll meet the organization

operating requirements. One of the main problem faced during the

development of a new system is getting acceptance from user .

Being a general purpose software there are no resistance from theusers because this will be more beneficial to the users.

5 . SYSTEM DESIGN

11

Project Report




5.1 Input Design

In input design, the user-defined inputs are converted in

to computer-based format. Input design involves determining the

record media, method of input, speed of capture and entry to the

system. The most important approach to the input design is

formatted and prompt design.

User side Input

The inputs provided by user are

• Employee code, name, age, salary

5.2 Output Design

Computer output is the most important and direct source

of information to the user. Designing the computer output should

proceed in an organized, well through out 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 efficiently.

When analysts design computer output they identify the specific

output that is needed to meet the information requirements.

Different methods for the information will be selected. Analyst

12

Project Report




creates document , report, or other format that contain information

produced by the system

5.3 Interface Design

Interface design mainly focuses on the design of

interfaces between software modules , external entities and the user.

The design of internal program interfaces, sometimes called inter-

modular interface design, is driven by the data that must flow

between modules and the characteristics of the programming

language in which the software is to be implemented. Externalinterface design begins with an evaluation of each external entity

represented in the DFD’s of the analysis model. Both internal and

external interface design must be coupled with data validation and

error handling algorithms within a module. Because side effects

propagate across program interfaces, it is essential to check all data

flowing from module to module to ensure that the data conform to

bounds established during requirements analysis. User interface

design has as much to do with the study of people as it does with

technology issues. Who is the user? How does the user learn tointeract with a new computer-based system ? So the system should be

developed in a user-friendly manner.

5.4 Procedural Design

A procedural design reduces complexity , facilitates change

( a critical aspect of software maintainability ), and results in easier

implementation by encouraging parallel development of differentparts of a system. Software with effective modularity is easier to

develop because function may be compartmentalized and interfaces

are simplified. Software architecture embodies modularity , that is,

software is divided into separately named and addressable

components called modules, which are integrated to satisfy problem

requirements. Modularity is the single attribute of software that

allows a program to be intellectually manageable. Monolithic

software ( i.e., a large program comprised of a single module) cannot

be easily grasped by reader. The seven important criteria that

13

Project Report




enable us to evaluate a design method with respect to its ability to

define an effective procedural design are, as described below

5.5 Modular Description

1. Add the employee details

The employee details such as code, name, age,

salary are entered by pressing 1 from the main menu and these

details are saved. The system prompts whether the user wants to

add more records .

2. Display Record

The user can see all the employee details, by

pressing 2 from the main menu.

3. Modify The Employee Details

If the user wants to modify the details of a perticular record, then the user

has to enter the code by pressing 3 from the main menu which represents the

record to be modify . The details are repeated to the user and after changing the

details. After changing the record the employee details are saved.

14

Project Report




4. Delete Record

If the user wants to delete the details of an particular

employee, then the user has to enter the ‘code’ of the employeehe/she wish to delete by pressing 4 from the main menu . The details are

displayed to the user and after delete it.

5. Exit

By pressing 5 from the main menu the user can exit from the

software.

5.6 Data flow diagrams

The Data flow diagrams was first developed by Larry

Constantine as a way of expressing system requirements in a

graphical form and this led to modular design.

A data flow diagram , also known as “ Bubble Chart “ has the

purpose of clarifying system requirements and identifying major

transactions that will become programs in system design . A DFD

consists of series of squares joined by lines. The squares represent

the data transformations and the lines represent data flows in thesystem.

DFD Symbols

1. A rectangle defines a source (originator) or designation of

system data.

2. An arrow identifies data flow i.e, data in motion . It is a pipeline through

Which information flows.

3. A circle represents a process that transforms incoming data flows into

Outgoing data flows.

4. An open re0ctangle is a data store , data at rest , or a temporary repository

of data .

6. IMPLEMENTATION AND TESTING

6.1 IMPLEMENTATION

The final and important phase in the system life cycle is the implementation

of the new system. The term implementation has different meaning , ranging, from the

conventions of the basic application to a complete replacement of the computer system.

The procedure however is virtually the same. Implimentations include all those

activities that take place to convert from old system to new. The new system may betotally new replacing an existing manual or automated system or it may be major

modification to an existing system. The method of implementation and time scale to

be adopted is found out initially. Next the systems are tested properly and at the

same time the users are trained with the new procedure. Proper implementation is

essential to provide a reliable system to meet organizational requirement. Successful

implimention may not guarantee improvement in the organization using the system, but

it will prevent improper installation. The implementation involves the following things

• Careful planning

• Investigations of system constrain

• Design the method to achieve the change over

• Training the staff in the change phase

• Evaluation of change over method

CONCLUSION

This project ‘ EMPLOYEE

MANAGEMENT SYSTEM ‘ deals with the Member addition

process, Edit, delete, search process for employee details. This

project is successful in meeting the goals of this concern, where

the manual system was not at their full satisfaction. By

computerizing the concern, the accuracy of the data recording has

been increased and the speed is also increased.

This system provides precise enlistment of employee’s information.

It records the customer details and give adequate information about

the employee. Data can be retrieved as and when required. It

creates different data and are stored. These files are also used for

further processes
