ABSTRACT
The
world over, it is indisputable that the introduction of computer technology in
different facets of life, has virtually transformed and entranced information
processing, which is very vital in any organization or parastatals of
government. Not only as a means of
information processing, the technology has also proved to be the fastest means
of information retrieval, which forms the nucleus of this study.
This work tries to x- ray the rate role of the computer in crime investigation as it affects the Nigerian police. Force it looks at ways of improving the information management of the force. This research work will cover the following areas: record information retrieval relating to MIS (Management information system), retirement Cretan for officers and crime mapping through a data bank of crime related information.
A detailed design of a computerized approach that will bring the much needed innovation is given. Also included in this work is a praper documentation for the new system design.
ORGANIZATION OF THE WORK
This project work is organized in seven chapters. Chapter one begins with an introduction of the project, a brief statement of the problem, the purpose of the study. It explicitly outlines the aims and objectives. Also the scope, limitations and constrains are also discussed. It ends finally with definition of terms; chapter two is specifically dedicated to literature review pertaining to the project work chapter three of the project opens with the description and analysis of the existing system. The fact-finding methods employed for the project is documented. The objectives of the existing system are highlighted, and the input, process and output analysis discussed the information floe diagram is shown, and the problems of the existing system and the justification for the new system discussed. Chapter four discussed mainly the new system design. The output specification and design and file design are respectively highlighted, also the procedure chart and system flowchart is illustrated. It closes with the system requirement.
Chapter five discusses the implementation of the new system. The program design, which consists of the program flowcharts and the corresponding pseudo code, are all highlighted. The source program is written and a test run is carried out.
Chapter six dwelt on the
documentation of the Q basic program for the new system. Chapter seven finally closes with
recommendation and conclusion. Attached
to this work are the FIIB (Federal Intelligence and information Bureau)
organization structure, the input and output forms for suspect confirmation the
references made to during research work are lighted.

CHAPTER ONE
INTRODUCTION
Information
Technology (IT) has set a new world order turning the world into a global
village, where information plays an indispensable role.
The Federal Investigation and Intelligence
(FIIB), is a special outfit of the Nigeria police force, as a role similar to
that of the FBI (Federal Bureau of intelligence) of the united states (US)
information they say is an indispensable force, and if we should go by this
maxim, it buttresses the need at which classified information is to this
outfit.
Over the years, this outfit had made
tremendous impact in combating crime, but in recent times, there has been an
avalanche of crime wave in the country leading to insecurity of life and
properties close investigation concerning crime activities reveals that this
special outfit of the police force is bedeviled with obsolete equipment.
Despite the glint strides taken by
this outfit over the years changing their investigation and recording equipment
to tape storage using cassette as recorder, there are still a lot of
surmountable problems which has hitherto, reduced the efficiency Bureau, Ogbor-Hill,
Aba and other division of the outfit through out Nigeria. The panacea to this may no doubt; lie in the
introduction of a properly designed computer base system which will bring the
much-desired automation hence, a prerequisite for being a member of the new
world order vis-à-vis information technology.
1.1 STATEMENT OF THE PROBLEM
The statutory duty of the federal investigation and intelligence Bureau (FIIB) is crime prevention and intelligence network which is solely based on information. This information received from conducted investigation, which should be supplied to the Bureau within minutes using electron communication. But this takes days or weeks and sometimes months if the investigation is carried in a distant area. The storage medium currently at disposal for information is susceptible to unauthorized access and damage. Most often, the recorded information is usually not within the reach when needed. Going by this high level of graft in the country, officers can easily remove: recorded information of a very serious crime activity by mere bribe offer. In view of the above problems which have attracted the author’s attention, he has unequivocally, decided to design a computer base system which will correct this abnormalities.
