    Grocery business is a kind of business that deals with the selling of food, and other household items.

    But, the purpose of a computerized information system in a grocery business activities. Which leads to accuracy speediness and also to ensure that all business records are intact.

    This project work looked into the problems emanating from the use of manual device in documenting records with the research area, analysis the existing system by the use of different investigation methods, designing a new system to suit the business enterprises and implementation of computer in order to enhance speed and efficiency of the business.

    Design and Implementation of a Computer Based Information System in a Grocery Store


    1.0 Introduction

    1.1 Background Of The Study

    Until quite recently grocery business in the country, were characterized as essentially background and a cog in the over all development of Nigerian economy. As a result of this, there has been prevalent feeling that such business could assisted, through information system.

    By definition, Grocery is a kind of business that deals with selling of food, and household items.

    Meanwhile, too little attention has been paid to the benefits that could be derived from helping grocery businesses to be computerized, mordernize and grow. This attitude arose partly from general ignorance and apathy amongst the grocery business owners and mainly from the very nature of the business, which made it difficult for its impact to be felt in the information system.

    However, due to much problem being encountered the running of this business activity manually, there is need to invent computers as an electronic method of running this business activities.

    The latent contributions in which grocery business enterprises can be make has now been recognized. This awareness in manifested in the large number of Nigerians who are now striving to put their personal ideas and abilities to effective use by starting Grocery Business. Another evidence in thie very fact that government in now direct its efforts towards the development of the sector of the economy by the use of information system.

    Inspite of its numerous advantages such as computerized information system, provision of employment opportunities, product of mini markets, quicker development of rural areas and the attention given to it by the government.

    The grocery business organization is still confronted with problems. One of such problem is no knowledge of information system, which in very important to do business, from the time a business idea in conceived of, to the promotional stage. It is therefore not purposing that the issue of information system and their design and implementation is a major concern to small business organization. The typical business man is always worried over the need of information system towards his business; as well as how to design and implement such business into information system. The problems will be looked into closely in this study.

    It is not worthy that most of the grocery business enterprises in Nigeria are sole proprietorship. Sole proprietorship, this is the simplest form of business, as the name suggests, there is on owner who in personally responsible for everything done by the business. He may have a number of people working for him, but the critical elements of ownership is in this hands.

    1.2 Statement Of Problem
