DESIGN AND IMPLEMENTATION OF A COMPUTERIZED COMMODITY EXCHANGE INFORMATION SYSTEM

 ABSTRACT

            The need to develop a Computerized Commodity exchange information system that will provide information and keep record of transaction made on commodities has become pressing due to the rapid growth of industries that make use of these commodities and the inefficiency of manual keeping of all transaction made.

            The information was got from the ministry of Agriculture, Ministry of Mines and power and Raw Materials Research Centre to develop a software package that would achieve the aim of this project.

            This software package is the project I developed to be useful to both large and small exchange market, ministries, industries, and other private establishments that use locally produced commodities especially those produced in Enugu State.

 

ORGANISATION OF THE WORK

            This section explains how the project is arranged.  The chapters and their purpose are carefully stated and easily understand how this project is designed.

CHAPTER 1 of this work is about the introduction and how the project come about.  It tells the problems and objectives of this project.

CHAPTER 2 tries to relate the project topic and some other topics.

CHAPTER 3 has to do with the investigation of the present system and its operations.  The evaluation of the existing systems.

CHAPTER 4 explain the design of the new system and shows chart of the different operation of the new system.

CHAPTER 5 explain the overall testing of the different modules of the program it also contain the program flowchart, pseudocode the source program.

CHAPTER 6 contain the documentation and manual that will help user understand the system orientation.

CHAPTER 7 the recommendation and conclusion the  appendixes that contain the program output and other necessary information.

CHAPTER ONE

 

1.0       INTRODUCTION

            commodity exchange information system Enugu State as a case study is an information system developed to provide necessary information about commodities produced in Enugu state.  It includes records of transaction made on these commodities.  These items range from Agro to mineral – based commodities of the state.

 

1.1       STATEMENT OF THE PROBLEM

            The problem has been largely on how to locate commodities where they are produced and the record in the state.  This includes grading of commodities. Standard measures and price attached to each grade.  This computerized system is aimed at providing a remedy for these problem areas.

 

1.2       PURPOSE OF STUDY       

            This study is of great importance to the entire public and me.  I will from the study develop in my area of study, and I will be enlightened more in the subject matter at hand.  Through the research, I will be experienced in my profession and from the interaction I made during interview with various individual in various offices concerning my research work.  I will learn a lot more things related to my project topic.

            The people in the area will benefit from this study.  The problem they are facing has been detected and a solution recommended.

            The new system will help to ease their burden in collection of data, store it and generate report if required for management decision and perharps for the development of the industries involved.

            Enugu State of Nigeria, make up local government area is endowed with many rich natural resources Examples are crops, vegetables, fruits, mineral produced coal, etc.  These resources are located in different town throughout the state, moreover individual, groups, commodities.  Hence there are business transaction taking place daily in these commodities.  These is therefore need to keep record of the information required on how to locate and buy these commodities when needed.  This when done manually can not give details of all that is required and involved.  Hence the need for this exchange system.

 

1.3       AIMS AND OBJECTIVES

            I have to recall here that this project work is an information system.  And as an information system, the aims and objectives is to serve the user with absolute information concerning the area is being built for.  Listed below are the collected aims of this project work as contained or the limit of my research.

(a)                To provide information on available commodities in Enugu State.

(b)               To provide information to the local government area and the warehouse at which those commodities could be got

(c)                To price for every commodity per unit measurement of the commodity

(d)               To allow updating of the database files of all the database in the system.

(e)                To provide information on the banks at which individual warehouse in local government area do their financial transaction

(f)                To provide security strategies to secure transaction and files

(g)               To produce report on information needed

(h)               To provide file maintenance facilities

 

1.4              SCOPE AND DELIMITATION

The commodity Exchange Information system is designed based on selected commodities existing in Enugu State.  The system does not take into consideration payment of any transaction made by cash, but that made through electronic fund transfer.  Banks which payments are made are selected ones situated in Enugu metropolis.

Mainly major commodities produced are taken care of in this project work.  There are no utility files or work up tables incorporated, instead a simplified and concrete users operation manual is provided to guide the user in chapter six.  This contains all the necessary utility facilities needed.
