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.
