Abstract:
“Employee Database And Payroll Management System” is designed to make the existing manual
system automatic with the help of computerised equipment and full-edged computer software,
fulfilling their requirements, so that their valuable data and information can be stored for a longer
period with easy access and manipulation of the same. The required software is easily available
and easy to work with. This web application can maintain and view computerised records without
getting redundant entries. The project describes how to manage user data for good performance
and provide better services for the client.
Introduction
The proposed project “Employee Database and Payroll Management System” has been
developed to overcome the problems faced in the practicing of manual system. This software is
built to eliminate and in some cases reduce the hardships faced by the existing system. Moreover
this system is designed for particular need of the company to carry out its operations in a smooth
and effective manner.
This web application is reduced as much as possible to avoid errors while entering data. It also
provides error message while entering invalid data. It is user-friendly as no formal knowledge is
required to use the system.
Human resource challenges are faced by every organization which has to be overcome by the
organization. Every organization has different employee and payroll management needs.
Therefore I have design exclusive Employee and payroll Management System that are adapted
to the organization’s Managerial Requirements.
Purpose
The purpose of this document is to describe the functionality and specifications of the design of
a web application for Managing Employees and their payroll. The expected audiences of this
document are the developers and the admin of the web application. Now with the help of this
system the admin has the information on his finger tips and can easily prepare a good record
based on their requirements.
Finally, we can say that this system will not only automate the process but save the valuable time
of the manager or the admin, which can be well utilized buy his institute. This will be an additional
advantage and management of power based on their free time from his normal duty.

4
Modules:
Admin
The Admin gets logged in by valid username and password. Admin can add new Employee, add
new Department, add new Pay Grade for the employees. Admin can set the ‘from’ and ‘to’ date
worked by an employee in a department with specific pay grade. The Admin can generate an
automated monthly salary of an employee. The admin can view all the past records of any
recorded employee.
Advantages
• It is cost effective as the user control the web application himself and does not go for
professional service.
• It saves time as it speeds up every aspect of the employee database management and
payroll process with a range of automated features.
• It is secure as the employee database and the payroll process is managed by the admin in
house rather than sending private information to a third party.
• Validating procedures and checks restrict user from making mistakes.
• The software is easy to use and is user friendly so no expertise is required.
• The calculations are automated so no chance of error.
Disadvantages
• It requires an internet connection.
• It requires large database.
FEASIBILITY STUDY

5
After identifying the scope of the project, the feasibility study is needed to be carried out. It is
basically keeping the following points in mind.
Building the software for meeting the scope: This software has met the scope. As there is no
data involved in the system, processing on the file, and the behaviour of this project is already
identified and bundled in quantitative manner.
The processing of this software is very simple as it has been designed in php and it has been well
divided into several functions according to the need.
Technically feasible: This software is very much technically feasible. This software is very much
concerned with specifying equipment and the software will successfully satisfy almost all the
admin’s requirements. The technical need for this system may vary considerably but might
include:
a. The facility to produce output in a given time.
b. Response time under certain conditions.
c. Ability to process data at a particular speed.
Therefore, the basic input/output of data is identified. So, the project can easily be build up and
it will also be technically feasible.
State of Art: The project is very much within the state of art since the project is a WINDOWS
based; it uses very modern and common technique.
Beside it is very much modern and user friendly. It also works as middleware i.e. only in between
the user and the file. So, it is completely a state of art project.
Financially Feasible: The project is very much financially feasible. The implementation and
development cost of this software under the reach of any college.
Moreover, it requires some training for the use. So, training cost can be neglected and the
resources of this software are very much available. It also reduces the labour and extra cost to be
paid for labour. So indeed, it is financially feasible.
Resources: As motioned earlier that the resources are easily available and the cost of training is
almost negligible. Sometimes situations may arise when it may not be so much easy. For a person
completely unaware of using a computer system could result in a training cost or for a very small
organization the purchase of a computer, instalment of the system and other charges may lead
to a difficult matter.

Features of Employee database and payroll
management system:
• Easy to use.
• It is completely secure.
• It is completely controlled by admin.
• This system is easily compatible with most of the web browsers.
• It is very interactive and saves time.
• Reduces paper works.
• Calculations are automated so it is highly accurate.
• Admin can view all the records whenever necessary with ease.
Future scope of the work:
• The option to print the records In future.
• I intend to add a leave structure in the future.
• I would like to implement a regular backup mechanism to back up the
employee database to avoid disasters.
• The system can be developed in such a way that its existing features can
be modified to better versions.
Conclusion:
This project is built keeping in mind that it is to be used by only one user that is the admin.
It is built for use in small scale organization where the number of employees is limited.
According to the requested requirement the admin can add, manipulate, update and
delete all employee data in his organization. The admin can add new departments and
delete them. The Admin can also add predefined pay grades for the employees. The
required records can be easily viewed by the admin anytime time he wants in an instant.
The payment of the employee is based on monthly basis. Numerous validations
implemented would enable the admin to enter accurate data. The main objective of this
framework is to save time, make the system cost effective and management records
efficiently.
