DESIGN AND IMPLEMENTATION OF A COMPUTERIZED DATABASE UPDATING SYSTEM FOR A TRANSACTION –DRIVE/OPERATION
A CASE STUDY OF NIGERIAN STOCK EXCHANGE (NSE) LAGOS
ABSTRACT
            Information is the driving force in a transaction driven operation decision, with rapid advancement in information technology the resulting increase in complexity of Nigerian Stock Exchange (NSE). The quality and variety of information needed for a transaction driven operation is increasing forth.
            We are now in computer age where our success and wealth will continue to grow through the use of computer to find solution to our problems. This project is concerned with the development of a transaction driven operation in a computerized database updating system in Nigerian Stock Exchange (NSE).
            Hence, provision for quick referencing, calculation, large information storage, data maintenance etc are also available.
  ORGANIZATION OF WORK
            Chapter one outlined the problem, definition, the purpose of the study, what the work is aiming at, the scope, limitations and assumption.
            Chapter two reviewed the related literature. Chapter three described and analyzed the existing systems, giving fact including materials used, organizational structure, objectives of the existing system. Both the input process and output analysis, giving the information flow diagram and stating the problems of the existing system with justification for a new system.
            Chapter four has the design of the system both output and input specifications and designs with file design, procedure chart, system flowchart and system requirements.
Chapter five is implementation of the designed system; having the program design and flow chart with its pseudocode, source programe and test run.
            Chapter seven gave recommendations and conclusion of the work.

  CHAPTER ONE
1.0       INTRODUCTION
            One of the most important device where computer application was achieved a remarkable recognition is in the area of transaction-driven operations. With respect to that having examined some problems is that retard the speed, accuracy and efficiency in a typical manual transaction-driven operation sector, attempts to develop a computerized method of handling a transaction operation in a big organization such as Nigerian Stock Exchange is to be embarked upon.
            However, if the program become useful and prove efficient contrary to the traditional method of manual handling of transaction operations. It should be such as a useful tool in computerization of other related for unsanctioned activities.
 1.1       STATEMENT OF THE PROBLEM
            Organizational problem contain hard and soft issues to varying degrees and the importance of the soft systems view point is that it avoids thinking use at solving problem in a machine like or mechanistic way. There may be a yearning for systems to behave in a controllable and predictable fashion but where people are involved, they will not often manage see situations in a narrow fashion and solve the more oblivious ‘hard’ problems, for example, about technology improved use of resource capacity, reduced administration cost etc. This is quite true of the fact the money unmated in printing out stock card, writing materials, hiring outside service is reduced.
            The classic paper on evaluating short term information is that of Boyd Cole and Khrashow’s James (1964). Both authors distinguished between the cost benefit approaches from their study model, they can put with physical performance of delivery time i.e reduction in information delay. However, in some business companies most of clerks have been accustomed to manual processing.
            Administrative business application refers broadly to those computer based system used in the exclusion and management of basic operations of an enterprises. They are distinguished for process control, information retrieval and management information systems by the category of operation they are intended to some. Mechandazation of these appliances has been and continues to be the most frequent reason what business organization install computer in the early days of computer use. Routine application such as payroll and inventory normally are the first to be computerized today, as organizations seek to solve more closely integrated areas of their operations. Highly complex computer appliances are being undertaken, for example, distribution management changes. When the real problem is about the human interaction.
            In other words, the problems a researcher will face in embarking on a research work may be due to capital, but most especially getting materials to source out the research work. Take for instance Nigerian Stock Exchange. This is one of the big existing company in the Nigeria and where to getting information about the company will be a very hard one.  At times wrong information are being given to researcher which makes the research work more difficult.
 1.2       PURPOSE OF THE STUDY
            The purpose of the study is to design a computerized database updating system for a transaction driven operation system.
            A computerized database updating system for a transaction driven operation will improve on the efficiency, effectiveness, accuracy, consistency and optimization on transaction processes.
            Another purpose of this study is to design a system that will replace the manual process and of course resolve inherent problems.
 1.3       SCOPE OF STUDY
            The scope of this study in limited to Nigerian Stock Exchange, Lagos. This study covers all aspect of a transaction driven operation. The use of computer has offered such great assistance, hence can make provision for quicker referencing, calculation large operation storage, data maintenance etc.
