1.1. BACKGROUND INFORMATION
In Ethiopia there is no any computer based method to handle day to day
activities of crimes happen. Since now we are trying to develop a system
that conveys good ways to handle those things. The Crime Management
System (CrimeManSys) provides optimal as possible as plan for crime
reports and managements. So many countries are faced with these
problems of crime reporting and managements of handlings. Now days
the members of peoples make crime are highly developed and educated
than police officers. To make more peoples are concerned to this and
help to stop crimes this system can improve knowledge methods of all
citizen become crime fighter.

 Persons make crime is more developed in technology than police officers
1.2. BACKGROUND OF PROJECT
The reasons that initiate us to develop this project is that we understand the
importance of technology in our day to day class learning and guessing where the
world is moving now. As well by guessing if our country police officers use
technology based methods struggling with criminals may reduce.

7. 1.3. STATEMENT OF PROBLEM

1.5.2. Limitation
Even though this project focuses on the crime reporting and managements
systems it doesn’t include the following because of time to do all this
 Not help to find perpetrators who abscond from the investigators
 It doesn’t bring the crime person to the court
 It doesn’t work without connection except reading article book
 It doesn’t upload videos or image but capture and send online

12. 1.6 FEASIBILITY STUDY
12
1.6.1 Operational /Organizational Feasibility
 It might not be possible to see fully operational system within the given limit of
time for software development. However with great cooperation of the project
team the system can address over all problems of the current system.
1.6.2. Technical Feasibility
 Usually new systems established in order to overcome the technical illness of the
previous system. In the same way, this system is technically big enough to be
applied easily to the problem identified in the existing system. In addition, the
both hardware’s and software’s for this system are highly available and can be
owned with small cost. Therefore, it can be concluded that the system is
technically feasible.

14. 1.7. SIGNIFICANCE OF PROJECT
14
 Police office can access their daily working zones easily using their mobiles.
 The placement of police officer will be effective.
 Minimize wastage of resources including energy.
 It speeds up communication and cooperation between peoples and police
 Automatically send message to the suspected person.
 Automatically send message for calling witness “Ragaa ማስረጃ”.
 Helps the investigating police officer to get fresh information.
 The system is portable.
 Helps to initiate investigation on priority basis.
 Enhances accuracy of information to be collected for effective use.
 Helps to perform the speedy trials.

15. 1.8. BENEFICIARIES OF THE PROJECT
15
In the future our system will be used by home and Law authority of Ethiopia.
Then when our project is successful we will have demonstration in front of set
authority and if our project is success then it will be used in overall Ethiopia.
Generally, When this project successfully implemented it is usable for the
community and Law authority.

16. 1.9.Methodology of the project
16
1.9.1. Data collection
Data collection is the most important part of the project to find the main
requirement of the system and to understand how the system works. We are
going to use different methods to collect data. Among the methods, we use the
following:
 Observations:- to analyze the organization the previous crime management
system
 Document analysis: - to get information about ways of crime managements
from 2nd district (ወረዳ) police office at Nekemte town.
 Interview:- for gathering direct information from the Commanders and other
polices

17. Cont…
17
1.9.2. Data Analysis
We are going to use object oriented approach and UML for the purpose of
analyzing the data. The main reason behind using OOA and UML is:
 In order to check reusability of the current crime management system in
Ethiopia
 In order to define new or modify objects that can be combine with the current
system

18. Cont…
18
1.9.3. Tools to use
The tools we are going to use for documents analysis in our
projects are:
 Microsoft office 2007, 2013 for the purpose of writing the
documentations
 Microsoft office VISIO professional 2007 for the purpose of
drawing the use-case, class, activity and other drawing.
During implementations we are going to use:

19. Cont…
19
1.9.3.1. For front end:
Android Studio version 2.2
JDK & Android SDK PHP
JavaScript WAMP
1.9.3.2 For back end
MYSQL

20. 1.10. RISK AND CONSTRAINT
20
1.10.1. Risk
While we are developing our projects we may encounter different problems
among:
 The computer virus and failures are some of them.
 Power fluctuations and loss in the laboratories if computer is desktop
1.10.2. Action Taken
As a problems exist the solution as well be exists. Some solutions for
problems are:
 Scanning the computer with antivirus and recovering the files
 Using additional laptop and working with them

21. CHAPTER TWO
DESCRIPTIONS OF THE EXISTING SYSTEM
21
2.1. Description of Existing System
The Current System of the Crime Management system is file based which is time
and labor consumer. The detector collect the data from peoples, blood strain, and
hair on that place. Based on thus data the detector and other police start the
working to gain information corning the criminals. Then they will continue till to
get the exact information then present in front of the court. Others are when
compliant is want to complain someone he has to come the police officer biro and
start to fill the compliant forms manually. To call the suspected person they will
print out the form then manually fill that form after that send the form with the
help of other person.

22. 2.1.1. The player of the existing system
22
2.1.1.1. Primary Actor
These actors are actors who directly initiate the system to run. We can classify this actor as
the main actor who plays the main role in the system. In the existing system these actors
interact with each other to fulfill the required tasks. Those actors are listed below:
 Commander (District Administrator)
 Criminal Detection Room
2.1.1.2. Secondary Actors
Those actors are who works under Primary actors. They do only what main actor order
them to do. Those actors are:
 Crime detector
 Comminuting police

23. 2.2. Major function of existing system with clear input, process and
output
23
The major functions of the existing system are namely:
 Assigning community police.
 Filling new police and complaint Information.
 Filling the new data of Community police
 Enter Zone information.
 Enter suspected information.
 View community police at different zones
 How the police officer get information
Input:-
 Crime happen at some place
Process:-
 After crime happen police will reach that place and start to investigate about the crimes by using
different methods
Output:-
 After some times the detector get the information’s

24. 2.3. Business Rules
24
A business rule describes how people think and talk about things.
Thus, defining a term is establishing a category of business rule.
Business Rule regarding the detectors
 The detector must be not talkative.
 The detector always try to investigate the truth about incidence
(crimes).

25. 2.4. Report Generation In Existing System
25
The report generated in the existing Criminal Management system is
somewhat in different manner. Those concerning number of
Comminuting police and society are always generated annually once.
Those corning criminal are generated weekly. That means the report in
the existing system are not computer based but they are written by using
paper, pen, as well pencil and other material used for drawing and
writing.

26. 2.5. Forms and Documents used in existing system
26
Totally the existing system is a paper based, that is time and labor
consuming works. Many forms used in this existing system are drawn by
pen and ruler. After drawing they start to fill the data’s concerning that
forms what they needs.
Forms are like:
•Adding new community police
•Adding annual renter and renting society
•Add suspected person form
•Register new police officer
•And others

27. Cont…
27
Documents are like:
 All day to day crime record of crimes
 Specific police investigation files
 Medical/traffic evidence and other written evidence
 Forgery-forged document
 Forensic/medical evidence certificate
 And others

28. 2.6. Problem of the Existing System using Pieces Fame Work
28
 Difficulty in report
 The officer dealing with a particular case cannot take decision by himself
even when he is having the firsthand knowledge/information about the case
and he can expect obstructions from higher authorities/officials.
 Even an efficient officer cannot/may not be able to handle more than one
case at a time.
 As we all know, a covered truth, Bribery plays an important role in the
existing system.
 Many cases are piled up in the corners, which are not proved, due to lack of
commitment in the job.
 In most of the cases, the innocent are accused in the existing system.
 And for more detail read documentation.

29. 2.7. Practice to be preserved from Existing System
29
This project will come up with a solution that can minimize the above
listed problems of the system in the country and enable the police officer
to be effective and efficient by considering the limited resources they
have. By considering those strengths of the existing system. We conserved
all the strength of the existing system already mentioned in the
documentation parties of our projects.

30. 2.8. Alternative options to address problem of the existing system
30
 Developing system that assign police officer to different zone.
 Storing updated information on the system.
 Better communication, better leadership, better training, and more
defined roles in terms of contribution to the society.
 Working with partners.
 Develop system that send message to suspected and witness.
 Develop system that store data of complaint.
 Develop system that register new Police.
 Reducing crime and disorder.
 Confidently and anonymity issues.

31. 2.9. System Requirements of the new System
31
2.9.1 Functional Requirements
 The system will allow insert police officer information.
 The system should provide password changing facility.
 The system should provide user authentication mechanism.
 The system should be able to generate report.
 Storing, updating and deleting records.

56. 3.5. Business rule of the new system
56
 The system works if and only if the required data are inserted.
 The member can’t create the double account using the same username
and phone number
 The system work connection based.
 It may increase false accusation unless the awareness creation is made.
 Physical presence of the person reporting a crime or the victim is
required to complete the investigation and frame a charge against the
suspect. This is because the Ethiopian Criminal Procedure Code
requires a witness to give his/her testimony in person; the testimony
should be read to the witness and finally signed by the witness.

57. CHAPTER FOUR
4. SYSTEM DESIGN
57
4.1 Introduction
Project design is the general approach given to develop the software to
solve the problem of a particular organization. Project design is the stage
at which description of project development is given and how the project
is designed. The purpose of design is to determine how to build the
system and to obtain information needed to drive the actual
implementation of the system. The focus is particularly on the solution
domain rather than on the problem domain. Object oriented design
consists of transforming the analysis model into the design model. It
describes the system in terms of its architecture.

58. 4.2. Class Type Architecture
58
Since our system modeling approach is object oriented, we have to
describe the system in terms of its architecture, such as its hardware
/software mapping, global control flow and persistency management.
Therefore, this session mainly concerned with the design part of Crime
management system.

59. Cont…

This figure presents a high level
layering strategy for software
application. The various layers
are represented by the rectangles
and collaboration between layers
indicated by the arrows. The
primary name of the layer is
indicated first, and other common
names indicated in parenthesis.

machines on one another.

63. 4.6. Data Persistence Management
63
Persistence data model or Entity relationship (ER) models are used to
communicate the design of a database, usually a relational database, to
both users and other developers.
Persistence are use the schema of database. The strength of persistence
data models is that data entities are conceptually the same as the table of
relation data base and that attributes are the same as table columns.
In the current database system we have used different tables as object
and each object is related to each other and enforced by referential
integrity by the use of foreign key and primary key.

4.7.1 Hardware Mapping
The hardware used for
registration system and
other service of the crime
management system is an
android based mobile or
personal computer.

66. Cont…
66
4.7.2. Software Mapping
The system uses Microsoft Windows 8.1
Operating System. That we are working
with. The proposed system uses sublime
or android studio as a text editor, PHP,
JavaScript, android parts as well we use
android studio rather than using
another IDE to develop the system. The
system uses MySQL server to store data.

70. Conclusion
70
 The manual system is adaptable and useful in the handling of crimes.
However, the automated CrimeManSys system is more functional because of
people automatically can report crimes around them in picture or video
format to the crime authority. In the aspect of speed, project design, accuracy
and stability with these features, an android based system crime management
can solve the primary problems being encountered during the Crime
reporting and managements.
 Our project is only a humble venture to satisfy the needs in our country.
Several user friendly coding have also adopted. This package shall prove to be
a powerful package in satisfying the requirements of the Crime Managements
in our country. On the last our project is still on going actually it is not
completely completed.
