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 V 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.
