Design and Implementation of an Information Management System for the Computer Science Department
Chapter One
OBJECTIVES OF THE STUDY
The major objectives of this study aimed at developing a system for the management of information others include
- To save time (fast inputting and accessing of records)
- To enable the management to plan ahead
- To reduce fatigue of the staff
- To ensure accuracy in the records of information
- To ensure the safety of the documents/records/data/information, the system will use passwords to reduce access.
- To ensure the integrity of the records
- To ensure consistency of accounts and reduction of errors due to damage to information
- To reduce forgery and loss of information by theft

LITERATURE REVIEW
INTRODUCTION
This chapter explores existing literature on previous studies and other related writings that have bearing with the present study. The review in this chapter is presented in parts with the followings breakdown.
REVIEW OF CONCEPT
CONCEPT OF INFORMATION
From the stance of information theory, information is taken as an ordered sequence of symbols from an alphabet, say an input alphabet χ, and an output alphabet ϒ. Information processing consists of an input-output function that maps any input sequence from χ into an output sequence from ϒ. The mapping may be probabilistic or deterministic. It may have memory or be memoryless.
As sensory input
Often information can be viewed as a type of input to an organism or system. Inputs are of two kinds; some inputs are important to the function of the organism (for example, food) or system (energy) by themselves. In his book Sensory EcologyDusenbery called these causal inputs. Other inputs (information) are important only because they are associated with causal inputs and can be used to predict the occurrence of a causal input at a later time (and perhaps another place). Some information is important because of association with other information but eventually there must be a connection to a causal input. In practice, information is usually carried by weak stimuli that must be detected by specialized sensory systems and amplified by energy inputs before they can be functional to the organism or system.
As representation and complexity
The cognitive scientist and applied mathematician Ronaldo Vigo argues that information is a concept that involves at least two related entities in order to make quantitative sense. These are, any dimensionally defined category of objects S, and any of its subsets R. R, in essence, is a representation of S, or, in other words, conveys representational
CONCEPT OF INFORMATION SYSTEM
“Information systems” concern the use of “information” by persons or groupings of persons in organisations, in particular through computer-based systems. A proper understanding of the nature of such systems requires viewing them in the context of the organisations that employ them. Consequently, concepts from a variety of disciplines are needed for describing any part of those systems and certainly for providing a sufficiently coherent picture of them as a whole.
This chapter attempts – in tutorial form – arriving at a pragmatic minimal set of interrelated concepts that may serve this purpose.
A fundamental problem when trying to reach consensus is the difference in philosophical or metaphysical position of those concerned. This does not only hold for the culturally different communities of information system professionals and information system users but even applies within those groups. They may feel that there is a common understanding of many general terms, for instance “world”, “thing” and “person”. Yet, even for these – and certainly for more specific concepts – various philosophical positions may be observed of how they areviewed. We will concentrate on just two of them1:

METHODOLOGY, SYSTEM ANALYSIS AND DESIGN
METHODOLOGY
Methodology is usually a guideline system for solving a problem, with specific components such as phases, tasks, methods, techniques and tools. A methodology can be considered to include multiple methods, each as applied to various facets of the whole scope of the methodology. There are several types of methodologies, such as:
- Structured System Analysis and Design Methodology (SSADM)
- Object-oriented Analysis and Design Methodology (OOADM)
- Prototyping
- Expert systems
Structured System Analysis and Design Methodology (SSADM)
Structured Systems Analysis and Design Methodology (SSADM) is an integrated set of standards and guides for the analysis and design of computer systems. It is an integrated set of standards and guidelines consisting of:
- Structural standards: which define the structure of a development project in the form of explicitly defined tasks, with clearly defined interfaces between them, and clearly defined tangible products;
- Technique guides: which provide development staff with a set of proven usable techniques and tools, and detailed rules and guidelines on when and how to use them and
- Documentation standards: which provide the means of recording the products of development activity at a detailed level.
CHAPTER FOUR
SYSTEM IMPLEMENTATION AND TESTING
IMPLEMENTATION
The new system is designed to be put into efficient use. Here, we will look into the various technical aspects that influenced the successful implementation of this system and determine the effective operation of the system. System implementation follows the approval of the system proposals and its objectives, thus it is to arrive at a satisfactory, implemented, completed, and function evaluated automated system. It also embodies the preparation of resources including equipment and personnel.
CHAPTER FIVE
SUMMARY, RECOMMENDATIONS AND CONCLUSION
SUMMARY
The importance or role of computerized management information system in the school premises and the department cannot be overemphasized. This study on management information system will be of immense value to the universities authority. This computerized information managementsystem will thus enable the university’s authority to make budget and provide services for the students within the revenue at its disposal. The system database that holds record of people or students that have cleared and have permit cards which are eligible for participation in academic activities and instead of the manual process and documentation of student.
RECOMMENDATIONS
I recommend this work to the management of Nekade University to replace the manual process of student information management system. Other institutions or establishment will still find this work important too because it will save cost and energy. I equally recommend this database to be strongly pass worded and accessed only by selected persons.
CONCLUSION
The benefits of using the computerized information management system in thecomputer science department are numerous. This is because the system will save cost, time and energy. It will eliminate forgery practices and the rampart cases of missing data or records.
