Abstract
EMPLOYEE MANAGEMENT SYSTEM Our project is based on problems faced
by a management of defense engineering college. The management faces problems
such as:
1. Knowing how many employees showed up to work on a specific day.
2. Knowing who worked on a specific agenda.
3. How long they took to complete their task.
4. Which employee is free to take up a new task?
In order for these problems to be solved, all employees will be registered on database
the time they clocked into work, which tasks they are working on and how long they
took to work on it will be recorded. The manager will be able to allocate jobs to the
employees. The system is web enabled and it will be possible to access it from
anywhere.

THE USER REQUIREMENTS DOCUMENT
INTRODUCTION
Employees are the backbone of any company, management of employee performance
plays a major role in deciding the success of the organization. The system is situated
in engineering college has a problem in management of employee performance. The
current system running in the college is paper based. That is the college is still using
cabinet files to store records of stock and employee information. Useful data is
scattered all over the place. In this chapter we shall discuss the solutions to the
problems being caused by the current system. We shall try to understand the
management expectations of the new system we are to develop for him.
DATA COLLECTION:
A questionnaire in the form of a survey was used to gather information. Why a
survey??The database program proposed for this project is based on major
universities’ performance. So similar colleges in Addis Ababa and were surveyed to
find out how they managed their employees. I asked them to respond to a few
questions. Their responses to the questions are summarized in Appendix A. These
were used to compare with the responses from the universities.
PROBLEM DOMAIN:
The problem domain is the computerization of an employee management system that
can be accessed online by the administrator and the stakeholders such as the manager.
THE CURRENT SYSTEM:
People have different personalities and work ethics. So in order to manage their work
efficiently and fairly, there has to be a system in place to allocate tasks to different
workers. Currently a manual system is used in the other colleges and universities in
Ethiopia that will provide most of the requirements for this project. The system used
in our college is based on “TRUST” the employer trusts the employees. Although
noble the manager has little it control over his work. In a manual system data is stored
in a cabinet. Files are thus often misplaced or lost. And at times is difficult to find
relevant files. Records for stocks are also not always filed correctly and thus
information is not centralized and not easily accessible.
EXPECTATIONS FOR THE NEW SYSTEM:
The systemshould be:
I. Secure.
II. The system should be able to provide a list of the employees, the times they
worked, the tasks they have been doing etc.
III. The system must be able to list what is currently in stock.

4
IV. The system must provide easy access to employees ‘details (name, id number,
employee number, address).
CONCLUSION
This chapter dealt with the user’s needs and expectations for the new system. The
next chapter deals with requirements analysis that is requirements needed to solve the
problem being faced by the defense college of engineering. An employee
management system will be the best solution for the problem. It will provide easy
online access to the employees that are currently at work and what they are working
on. Also easy to allocate jobs to the employees that are done with what they were
doing. The system will provide quick and reliable access to the running of the
business saving the manager a whole lot of time and money

REQUIREMENTS ANALYSIS DOCUMENT
INTRODUCTION
In the previous chapter the user requirements were collected. In this chapter the
requirements will be analyzed. All the software development tools that will be used to
implement the system will be identified.
PART I
DESIGNER’S INTERPRETATION OF THE PROBLEM
The manager and stakeholders would like to have remote-access to the employee
system application. This means that it has to have a web-based interface but should
also provide an interface for a mobile device. The data will be stored in a database.
HIGH LEVEL CONSTITUENTS PARTS
The system will consist of two constituents. That is Software management and
database management. Database management will be managed by the
manager/administrator. Here are features or characteristics of these two constituents:
DATABASE AND SOFTWARE MANAGEMENT:
I. Will be accessible on different devices or platforms.
II. Will be to add or delete from database.
III. Will enable retrieval of data from the database.
IV. Will enable searching through the data and make reports from his findings. Below
is depiction of how the users will interact with the system:

5
V. Will enable editing of data on the database.
Below is figure 1.1 which depicts how the users will interact with the system:
EXISTING SOLUTIONS
There similar systems to employee management system. For example:
• Macros
• Pastel HR management.
• Halogen software (Strategic talent management).
ALTERNATIVE TECHNICAL SOLUTION
With the legacy system in mind, there is need to computerize the whole system to be
flexible.
BEST SOLUTION
The best solution will be an online database which will be flexible for the manager to
access wherever he is. He can access from his mobile device (Laptop or cell phone). It
can be achieved by making web- based software. For better planning we shall break
down the work load in form of model and technology to be used.
MODEL
In order to put into consideration all, the needs of the user, we will use Unified
modelling language (UML) to model the system. UML will act as a blueprint to the

DBMS
Application
Program database
system

whole system we are going to implement. UML will help me to break down the scope
of the whole system so that it’s flexible to implement the system.
 SYSTEM TESTING:
WHITE BOX TESTING
This is a verification technique for software developers use to examine if their code
works as expected. We will use this method to detect errors during software
development. White box which is also known as clear box helps in optimizing of my
code. Using the aspect of unit testing we shall be go through each and every line of
code. This makes it easy for us to remove extra lines of code that can bring about
hidden errors.
USUABILITY TESTING
This is a technique used to evaluate the quality of the software. This is where
random users are used to test the product using different data and their response to the
system is put into consideration.
BLACK BOX TESTING:
It is also known as functional testing. This technique is used to test the complete
system. Black box testing ignores all the whole system components and focuses only
on the outputs generated for a particular input. Different data will be used for each
function to check if the right output is gotten. This is to check the behavior of the
system as per different input data.
CONCLUSION
Employee management system (EMS) is going to be implemented usingPHP, My SQL,
Apache and PHP My Admin which are all open source applications. They are all a
solution to
web based system. WHY?? After examining all the possible solutions, we decided on a
web
based system to address this problem.

Figure 2.3 shows employee registration process. We have three actors in it,Employee,
Admin and Manager. Applicant provide requirements, admin register him,and manger
create him attendance of working days.

10
Figure 2.4 shows Employee attendance marking flow. Just login to the system with
his/her account and mark attendance of current work day.

11
Figure 2.5 shows salary payment process, three actors are involved, Manager,
admin and finance. Manger calculate net salary, admin approve it and finance deliver
to employee.

12
Figure 2.8 shows sequence of functions for employee recruitment. 4 Objects are
involved: Applicant see jobs then send application, recruitment committee analyze
application and schedule it, applicant give test and/or interview, if passed then
informed from recruitment committee that he/she is recruited.

CHAPTER 3
USER INTERFACE SPECIFICATION:
INTRODUCTION:
The previous chapters dealt with the user requirements specification. This chapter
documents
the current user interface and the various elements needed to fulfil the user
requirements.
The images of the user interface pages are included to demonstrate the application’s
look and
feel.
DESCRIPTION OF COMPLETE USER INTERFACE SPECIFICATION:
The Login page:The main screen will contain the login page (See Figure 1.2). The
main
screen will contain the login page. The login page consists of college link, contact link,
Employee id, password and the login button. It consists of two text boxes that are
employee
id and password. There is also a submit button with the value login. The contact link
leads to
a web page that contains all the contact details of the administrators. The college link
also
leads to a web page that gives a brief history of the workshop.
Figure 1.2

20
Application page:
There will be two kinds of users. They are employees and administrators. Once an
employee
is logged in, they are only able to view but not update anything in the database. They
will be
view links for:
• Work hours
• Contact details of fellow workmates and their own
• Holiday days they have left.
The feedback page:
shows the feedback after clicking on the work hour’s icon. This show all the employee
personal details. This however doesn’t allow the employees to change anything.
The administrator’s application page on the other hand has very many different options
mainly:
• Salary link: This deals with all the aspects concerned with salary of each individual
employee. That is deducting taxes and insurances on their monthly allowances.
• Employee link: This deals with adding, deleting and updating all the employees’
information.

21
HOW THE USER INTERFACE BEHAVES:
When users input their username and password these must be authenticated before
access is
granted to the various applications. An error message is issued when the user enters the
wrong username or password. The error message prompts the user that they have
entered the
wrong username or password. In the case of correct password and username then the
user is
gains access to the application that they are privileged to use. the employee will only be
able
to view and edit his personal details and that of his /her emergencycontact. On the other
hand, the administrator is privileged to use all the functionality of the application.
Figure 1.3
shows the use case diagram of the system’s functionalities
CHAPTER four
HIGH LEVEL DESIGN
INTRODUCTION
This chapter concentrates on the object oriented analysis (OOA) or high level design
of the problem. In this chapter every object is described and documented and the data
dictionary provides the detail of all the objects. The class diagrams will show how the
subsystems interact with each other. Furthermore, the objects, attributes and methods
will be identified.
Data dictionary:
A data dictionary is a collection of descriptions of the data objects or items in a data
model for the benefit of programmers and others who need to refer to them. The
dictionary gives a brief description of the objects that will be needed to form the
online employee management system.

22
Detailed breakdown of the technical solution Employee details Object:
This contains employees’ personal details and qualification. This object contains
record for only one employee.
Conclusion: The data dictionary described the attributes and the data type. In this
chapter, each class and its attributes are explained in detail using a data dictionary.
The ERD explains the relationship between the different classes and attributes that are
needed to implement the user interface. In the next chapter the object oriented design,
which is also known as low level design will be discussed.
Chapter 5
OBJECT ORIENTED DESIGN (OOD)
Introduction:
In the previous chapter, each object was described and documented in terms of a
data
dictionary. In this chapter, the Object Oriented Design (OOD) will be described.
The data
types for the attributes, the algorithms and implementation particulars of each
class etc. will
be explained. The OOD will present all the classes mentioned in the OOA in terms
of
pseudo-code. The state diagram and sequence diagram will also be explained in
this chapter.
The inner details of class attributes (data types) and methods (functions): The
ERD (See
figure 1.5) defined in chapter 4 shows all classes/tables that will be used inside the
system.
Also data types were well-defined in the data dictionary and functions are
pronounced within
the ERD.
State Diagram: The state diagram (See figure 1.6) portrays the dynamic
performance of login
and application functions of the system. Both the employee and the administrator
log in using
the same applicationpage. So boththe users enter the username and password, and
then the
system authenticates the entries. If valid the user is recognized by the system or
else the user
is rejected. The user then selects an option and if he is privileged to use the option
then the
system confirms it. The state diagram below explains it all:

23
The event diagram or sequence diagram: (See figure 1.7) Demonstrates the
sequence of
activities where the system is in operation.
Pseudo code:
CONCLUSION: This chapter undertook the pseudo-code showed an outline of
programs,
written in a form which is clear and which will be easy to convert into a
programming
language. It also covered the state diagram and sequence diagram
