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



                                                                    5
constraints       poses     a    lot    of     problem.         Business

      Furthermore, business enterprise of information

is categorized into business and policy.                     The budgets

and    capital         investment      analysis        are     financial

information        whereas       information          generated        from

processing of transaction data are of accounting.



1.1 BACKGROUND

      In   the    early     days,     before    the    advert     of    the

Europeans,       the    people   in    Nigeria    were       engaged    in

various     kinds      of   occupations        which    were    greatly

determined by factors such as geographical location,

nature of the land and the cultural background of the

community.




                                                                          6
       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

       The    objectives   of   the   project   work     cannot   be

over     emphasized.       Objectives     of     an    enterprise



                                                                   7
information      ranges        from   management   planning      and

control which involves operation of all levels of

administrator in an organization. It also aims at

improving       transaction           processing    cycle,       its

objectives tends in achieving a standard financial

information      such     as     budgeting    system    an   annual

report.



1.2.1     PURPOSE OF STUDY

    This researcher aims at making basis for setting

prices    or   for   choosing         which   capital   assets    to

purchase.      Another purpose of this study is to design

a small business enterprise information system that

determine the information management requirements and

must respond quickly to change on those requirements.



1.3 JUSTIFICATION FOR THE PROJECT




                                                                   8
    It        justifies          us    for     creating      employment

opportunities,           they     offer    different     apprenticeship

training       to        the    unemployed.          Because   of     the

diversity,          it         promotes      economic     growth      and

development, it reduces the waste in the society by

using scraps from big firms.                  It supplies the masses

with the needed goods and service, it also encourages

self empowerment.              The OPEC has really helped in the

business enterprises of this nation by making sure

that Nigeria has full control of her oil resources.

There    is    increase          in   commercial     activities     among

member states due to remove of restriction to free

trade.



1.4 SCOPE OF THE STUDY

    This project study tends limit this research to

the financial information of the business. Financial

information         is    generated       directly   a   by-product    of



                                                                        9
transaction    processing.            But,   this   work    does   not

depend    solely      on     by-product      information.          This

project tends to considered other factor which are

important     in     the     design    of    effective      financial

information        thereby    producing      a     proper    business

enterprise information system for implementation.



1.5 METHODOLOGY

       Methodology as the word goes the procedure of

research and is perhaps the truth of the research

report.       It    is     also   defined     as    an   operational

framework within which the facts are placed so that

their meaning may be seen more clearly.

There are three types of survey methods namely:

  1.     Historical method

  2.     The descriptive method

  3.     The analytic method




                                                                     10
  Based   on   this     project       the   method   used   is   the

descriptive survey method where all data were simply

observed by the researcher.
