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 case filling system for drug monitoring Agency. It looks at ways of improving the information management of the Agency. This research work will cover the following areas: record information retrieval relating to MIS (Management information system), 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 paper 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 flow 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 Visual Basic program for the new system.

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 National Drug Law Enforcement Agency (NDLEA) is an agency whose responsibility is to detect and arrest drug addicts and traffickers for necessary prosecution according to the law. 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 drug related crimes, but in recent times, there has been an avalanche of drug trafficking and usage in the country leading to insecurity of life and properties close investigation concerning crime activities reveals that most offenders were under the influence of drugs hence the importance of this Agency and the upgrading of their obsolete equipment to meet with the international standard.

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 of the outfit through out Nigeria. The panacea to this may no doubt; lie in the introduction of a properly designed case filling 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 National Drug Law Enforcement Agency (NDLEA) is a drug prevention and intelligence network which is solely based on information. This information received from conducted investigation, which should be supplied to the Agency 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 case filling system which will correct this abnormalities.

1.2 PURPOSE OF THE STUDY

Having been aware of the numerous anomalies which have reduced the efficiency of The National Drug Law Enforcement Agency (NDLEA) the purpose of this research is focused on designing and developing a computerized based case filling system.
