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, has the technology 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 proper 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.
