1.0     INTRODUCTION

The traditional management as well as organizational behaviour and operation research theories agrees that the organization provides the system and decision centers for decision-making.

Information as a data has been transformed through some process either (mechanical, electronic, mathematical or human) into an information system, with the view of achieving a good.

Information system in many organizations has various definitions due to several discipline, but in this research work, information system is defined as it relates for a small business enterprise.  It all involves the flow of data within the organization for effective decision making.  The neglect of a business enterprise information system due to economic constraints poses a lot of problem.  Business enterprise information system comprises of sub-system which includes purchase system, management a well as planning system.

People living along the reverine area engaged in fishing and net making, others hunted, made clothes and built different kinds of shelters, while people with vast areas of arable land farmed and produced both food and cash crops. Still others engaged in creative activities such as carving, metal work and black smiting.  People specialized in their various areas of endeavours and exchanged their products with one another. Trading them was by barter whereby goods were exchanged with goods.  For example, a farmer gives a shoemaker twenty tubers of yarm for one pair of shoes, a fat goat for a pair of trousers, this was called barter system.  It had a lot of inherent problems.

1.2     OBJECTIVE OF THE PROJECT

1.                 Historical method

2.                 The descriptive method

3.                 The analytic method

Based on this project the method used is the descriptive survey method where all data were simply observed by the researcher.
