COMPUTER APPLICATION IN PROJECT TRACKING INFORMATION SYSTEM: One cannot conceptually discuss management system without computers it is the power of computers that make management information system effective and efficient. The question is not whether a computer shall be used in management information system, but the extent to which various processes should be automated. The idea of an automated information and decision does not mean computer automation but implies that some concepts of takes are best done using computers.

The manpower and computer are concatenated to form a system with results being obtained through a set of dialog and instruction between the computer and human brain known as processor

2.2 COMPUTER DATABASE IN PROJECT TRACKING INFORMATION SYSTEM.

The development of corporate database will be one of the most important data process activities in many years to come. Date will be increasingly regarded as a vital corporate resources which must be organized so as to maximize their value. In addition to the database within an organization and government, a vast new demanded is growing at a staggering rate. The growth rate in size of computer storage is greater than the growth in size or power of any other component in the exploiting date processing industry.

Frequently, one sees systems, today in which database design decisior where made in a shortened manner. Indeed in many situations, straight forward design calculations do not provide the answers because there are intricate trade-offs between one aspects of the design and another trade-off, for instance between storage utilization and time utilization, between response time complexity of data structure, between design which facilitates unanticipated inquires and design for well defined operational requirements.

2.3 MANUAL FILLING OFFICE DOCUMENT

Onibonjes defined filling as the orderly collection, management and safe keeping of information and prompt retrieval of such information as at when required for any decision that fits both manual and electronic filling. This system serves as a living memory of the business which can be referred to at any time by anybody. It is the view of our author that the filling system generally is a ready source for future action

Obibonoje argues that a good filling system must have the following attributes.

it make for orderly collection of papers and documents used in the business

There must be preservation of the materials thus collected swift retrieval or relevant informant without any delay irrespective of who many wish to retrieve such materials either old or new hand materials. The person has all it takes to be secured and otherwise operate the application. This according to him requires simplicity of both to understand and to operate an optimum cost because of the inability of most filling systems to meet these, attributing the call for an electronic filling of office documents in many commercial organization as necessary.

This has been a general argument in the business and commercial quarter that a large part of the efficiency of an office depends not only on the existence of a reliable filling system, but also on the competency of staff in the art of methodical filling and indexing. Prominent in this pattern of argument are Harrison Odina and Fosu, in their work secretarial duties in which they developed general rules for filling.

ELECTRONIC PROJECT TRACKING FILLING

Filling system can be manually or electronically designed.

We seek to examine the application of the project tracking filling (PTF)

In the subsequent chapters. This means that some electronic devices are involved in an in-dept knowledge of these as if it applies to the user a necessary. For instance, the computer is an electronic machine that manipulates data with manipulation and storage of data, it communicates with other computers with other types of device or machine also with human beings who manipulated them.

Penguin English dictionary sees computer as A machine that memorizes, sift, analyses and co-relates data and of the same time produces selective information as required Another dictionary view it also as any machine which can accept data in a prescribed form, process the information or date and supply the results of the processed data in a specified format as information or as signals to control automatically some further machines or processes this is according to AB chandler dictionary. There are also more definitions of computer which store, control and handle data are communicate to other devices and that of filling of project documents which can be automated.

However, studies carried out by the same scholars in 2009 have shown that the need for computers are very necessary in terms of speed, accuracy, reliability, versatility and automatic response. This is the main reason why the glamour of electronic filling of office document in the modern era of government. Computer is by far faster than human being solving the same problem, thus its usage enhances easy execution of tasks in a better and faster way. The computer is always accurate; it could give the same result to a problem at any point in time provided the same program is given. Computer shares large amount of data on external storage devices such as disks, tapes, flash, compact disk (CD) for future usage.

Newton in his own contribution argues that, the data and the method available for the electronic filling and retrieval of office information have been shown to catch on. However according to his, he said that there are number of indications which suggest that electronic organizations should now be serious considering electronic filling it associated benefit. But for him, electronic filling has become chapter while paper based system has a proved increasingly more expensive to maintain and has given better rooms for electronic system which has given better responses, limiting of time, office space, labour and above all the cost of keeping ideal filling cabinets which have increased dramatically. The author when on to reveal how the generation of information which is fast and accurate is being made easy and cheap to every offices, organization and institutions. He revealed also that it was a result of digital computers which increase tremendously in offices, institution and in government to get increased in their electronic mailing system and other digital communications.

Newton went ahead by contending that information has not only increased in volume but also become more valuable. Besides being expensive, papers based system encourages duplication and can hinder effective distribution therefore the increase number of screens now installed makes it more feasible to attribute information in an electronic form. Therefore this makes Newton to electronic information generated by word processing and data processing systems, the bulk of information in todays offices is still on paper or paper based.

Osuagwu O.E (1996) agree with Newton that manual processing of information system utilizes electrically powered machines to produce a variety of financial recodes and reports. Paper based filling can be automated by the use of electronic data processing (EDP) which uses called peripheral equipments. This EDP system makes possible a high degree of accuracy but contends that errors are prone to occur through the programmers or operators omission. The input data may contain error or computer program may contain logical or syntax errors. The author insisted that when EDP is in place, a system of internal control is necessary to ensure reliability of computer output.

Ejike (1996) in his paper summarized the benefits that may occur from a carefully planned and properly administrated electronic filling of office documents. He says also that the use of electronic device in organization or government clears up confusions and reduces the potential for miscommunications and envisaged in manual filling. This he says can free management to spend its time more on productive and creative work. But he argues that a well prepared automation filling will equip the management team with the information and support need to do their job. Carefully record keeping generally promotes responsible proactive management because carefully proactive planned electronic filling system will be a valuable management tool that would benefit any organization and government regardless of its shape and size.
