Consequently, the thesis was prepared in view of showing how computerized purchasing information system can enhance the processing of records, storage of records and files, retrial of files and the updating of purchasing files. It also establishes the advantage of the computerized purchasing information system over the manual system in Eastern shop limited Enugu.

ORGANIZATION OF WORK

This study has been organized in seven different chapters. Chapter one trashed out the statement of the problem, background of the study, purpose of the study, its importance, scope, limitation, assumptions and definition of terms.

Chapter two review of related literature which chapter three dealt with the description and analysis of the existing system. The first finding method used, organizational structure, objective of existing system, input, output analysis, information flow diagram, problems of the existing system and justification for the new system.

Chapter four presented the design of the new system. Its out put specification and design, file design procedure chart, system flowchart and system requirements.

Chapter five cooked into the implementation, the program design program flowchart, pseudopodia, sources program and test run.

Then chapter six was the documentation.

Chapter seven borders on the conclusions and recommendation of the work. After which the reference comes last.

INTRODUCTION

1.1    BACKGROUND OF THE STUDY

The art trading in materials i.e the process of buying and selling is nearly as old as man himself. Before the advent of money as medium of exchange man bartered item surplus of his requirement for things, which he needed? From the time discovered that he could put his talents to produce or manufacture things, he began to specialize on whatever was his vocation, man found it more economical to purchase materials of quality suitable to his needs at prices which he considered favorable.

It was observed that 50 to 60 percent of eastern shop expenditures is on materials. The purchases department therefore, becomes the biggest spending department of the eastern shop. Materials and supplies form the life blood, as it were of an industrial concern. These should be made available on proper place, time and at proper price.

Since materials constitute the largest chuck of the cost of the creation of value (for which alone to customer is willing to pay a price), it is necessary for the purchase to exercise at most prudence in ensuring for the purchaser to exercise at most prudence in ensuring that the best ultimate values is obtained for every ripe spent on material VFM (Value of money) has to be the slogan of the purchase department.

Today purchasing is not the dame as buying of yester years. Buying is money the act of procuring at item of material at a price. On the other hand purchasing function is the improvement of profit and actively searching out and implaning new ideas for improvement of the company’s product achieve this objective by cost of material. Finding out substitute materials that are more economical, by eliminating element of cost in purchasing that do not contribute to value and generally ensuring a higher degree of effectiveness in managerial performance functions righ form participation, working capital management and profit improvement.
