DESIGN AND IMPLEMENTATION OF A WEB BASED NITEL TELEPHONE BILING SYSTEM

ABSTRACT

This application of computer in various fields has eased a lot of problems encountered in the use of manual system in the various disciplines of like. It is as measure towards addressing this issue that this project has primarily billing system that could get rid of all the shortfall. In this project the researcher have analyzed the manual system and also identified some of the problems and limitation which scene to hinder the realization of the goals of the existing system.

With regard to this the author has designed a kieb based telephone billing system to help minimize some of the problem inherent in the manual system. To bring the subject matter to pictorial form the user to appreciate more flow diagrams to be seen in subsequent chapters, more so this write up is mainly to introduce the reader to what main from can do especially in telephone billing system using Nitel Nigeria Plc Benin city as a case study.

CHAPTER ONE

• INTRODUCTION

Computer has proved its uniqueness in different works of life. It provides and in different ways reduces complexity and generate.   Maximum output.   This made possible through the unique features of computer system in the areas of speed, information storage and retrieval automatic is the important faced of economy in the society. If provides adequate communication causes great place havoc in the society.   The nature of communication determines the mode of transmission.

Communication through the telephone system is one of the fastest and most reliable modes of message transmission.   Through the telephone system, information can be cone eyed quickly and adequately.   Information gets to the destination immediately and the sender receives feedback at the same time.   Information storage and retrieval is also achieved through the telephone system.   Information can be stored in the absence of the receiver.   The receiver can also retrieve this information at any time.   Acquiring the phone for use is by subscription. Individual or groups that wish to acquire phone always subscribe through the organization in charge.   Information about every subscriber is taken and stored for reference purpose.   Phone subscriber pay bills according to the calls made.

The outmost speed at which the universe is being turned into a global world is attributed to the sophistication in the telecommunication industry. These radical changes have been made possible by the intention of digital technology in electronics and telecommunication analogue.   This means that the signals being handled, processed or transmitted are presented by voltage whose amplitude quinsy vary continuously with time.

Consequently, in the telephone system the transmitted signals an direct representation of the speech waveforms.   This did not provide the easy and continuous flow of soured wave in the system.   This project is aimed at developing a system that will help in the billing section of NITEL (Nigeria Telecommunication Benin) to enable serve it customers effectively. Bill them accurately and also give customers details of how they are being billed.

1.1     STATEMENT OF THE PROBLEM

The quest for more sophisticates and affective system that can handle the telephone bills of the customers in telecommunication companies has led the researcher to the designing and development of software to handle the telephone, subscribers do complain of excessive billing and this has often been traced to the carelessness or otherwise on the part of the staff that prepare the bills. The carelessness of staff that results in the delay and stoppage of updating the customer’s bill account is another factor. Also, lack of working materials e.g. carbon sheets, stationeries and also laziness in the repairs of faulty machines is often complained about.
