DESIGN AND IMPLEMENTATION OF A COMPUTERIZED AUDITING SYSTEM FOR A FINANCIAL INSITITUTION
A CASE STUDY OF DIAMOND BANK (NIG) PLC
 ABSTRACT
The documentation management system in most audit firms no doubt, has a difficult task in today’s competitive auditing industry; hence there is the need for a fat, more efficient and effective processing system.
Client’s files cannot be assessed quickly, and many difficulties are experienced in the updating, verifying and other auditing jobs.
The work is geared towards the computerization of the existing system of processing data as well as identifying the various problems which are encountered the manual and mechanical method of data processing in the auditing of a clients financial statement of account and to recommend a first class solution to these problems which is to computerize the auditing/ processes in the banking sector,
The thesis as well compares the existing system, with the new system, which is the accurate and a faster means of processing data and the problems faced in preparing a customers financial statement of account. This alternative will provide a clear and urgent answer to the problems encountered in the auditing operations and hence fill private and government organization, industries, banks etc with reliable alterative functions assurance and dependability of financial statement about the account of the bank.
The justification of this lies on the use of manual auditing operation. Finally, the thesis was concluded with the implementation programming, text run and changeover process of the new system.
 THE ORGANIZATION OF THE STUDY
This study only focused on the computerization of the existing system of processing data as well as well as identifying the various problems, which are encountered in the manual mechanical method of data processing in auditing a client’s statement of account.
Chapter 1 comes the introduction statement of the problem, purpose of study, aims and objectives, limitations, assumption and definition of terms.
Chapter 2 deals with the literature review.
Chapter 3 Analysis of the exiting system, fact finding method, organizational structure, objective of the existing system, input process, output analysis, information flow diagram, problems of the existing system and justification of the new system.
Chapter 4 covers the specification design, input specification and design, file design, procedure chart and system requirement.
Chapter 5, which is the implementation, comprises of program design program flowchart, pseudocode, source program and test run.
Chapter 6 covers the documentation,.
Chapter 7 covers the recommendation conclusion and references.

  CHAPTER ONE
INTRODUCTION
Auditing is an activity or exercise that implies an incept examination of a set of financial statements, so as to form an objective opinion which is expressed in the form of an audit report the financial statement about the transaction of a business organization.
Prior to the introduction of computers, auditing was done expansion in business and organization; it became increasingly difficult and cumbersome to accelerate auditing processing. Files and documents containing information about the business or organization being auditing increased in a number and also was hard to keep as they occupy space. Auditor suffered tremendously because of this.
 This came with the intervention of computers, widely used today n all areas of human and be it in production, manufacturing, finance purchasing, and auditing resources among others.
The incessant increase in the use of computer in the public and private sector of the world economics is a clear manifestation of the efficiency of the operations in achieving results.  
However, the ways of auditing manually in recent times has been confronted with the problems of error traceable to human mistakes and share comings thus overcoming these problems with computer is what the researcher is going to consider in this research work.
 1.1    PURPOSE OF STUDY
The researcher deemed it necessary to carryout this work so as to point out those areas that are associated with manual auditing and also it creates measure to take in other to alleviate the problems.
This work or study will be vital in various ways to a number of people including the businessmen, firms, organization, companies in th filed of auditing. This will be of immeasurable benefit to auditors from times to time.
1.2       AIMS AND OBJECTIVES
 In order to keep auditing a breast of unreliable records, then there should be the thirst for reliability and credibility of information and records that facilitate capital business operations, firms and organizations proceed to establish and implement computerized measure and alternative to the present auditing.
The aims and objectives that are involved in investigating on the alternative to manual auditing operations are to provide for security against dubious minded managers as well faulty and unreliable records.
This work will as well serve as a stepping-stone to other researchers in the area of auditing and thus it will help to improve on this work, so that greater findings and recommendations will be made under auditing.
 1.3    THE SCOPE OF THE WORK
This research only considers how problems of auditing manually in the area of financial organization be it private or government owned could  be extremely reduced or alleviated.
The researcher will look at the existing nature of the problems and then suggest ways to enhance them.
I will equally look at some manual auditing processes but may not go further to expose some auditing problems because of certain circumstance
