CHAPTER ONE

1.0     INTRODUCTION

          One of the most exciting aspects of the information technology revolution is the combining, telecommunications with computing. This allows information to be processed by computer and then transferred down telephone lines to the recipient computers. The speed at which this can be done surpasses more conventional communication techniques. The process is no longer limited to telephone.

The combination of computer and telecommunication technologies has heed profound effect on the way computer system are organized.

NITEL (Nigeria Telecommunication Plc) is one of the organization that gives communication services to subscriber (Although there are presently other private driven communication services subscribers.

NITEL has the list of all its subscriber in a book where they keep records of each subscriber in a unique way. Periodically when new subscriber come in, they update the book let it become a routine when a subscriber comes in or leaves to update the booklet.

This way of producing information or producing of this booklet will always be hindered since manual operation is involved and most time, it be can become error prone and then misleading people.

This booklet is known as TELEPHONE DIRECTORY which is the fulcrum or pivot of this project. Since computer revolution involves and covers all works of life just as we have said earlier, when adopted and it replaces the manual method of processing, there is indeed going to be a complete revolution in the system.

Using of key fields for searching and retrieving of any viable information of any subscriber will be easer and fast.

STATEMENT OF THE PROBLEM

          Many people lacks the will to read books either of small or large size. Unfortunately, the telephone Directory in a voluminous and it become tasky to search through such text and moreso it involves lot of time.

Inflexibility of this manual system is nothing to write home about hence computerization of the system becomes imperative and nothing to ignore because it is not easy to modify or update information.

Finally, another problem facing this system is the cost of production. It is always involve much money to produce booklet of telephone Directory.  The maintenance also involve using the money and they all are carried out periodically.
