Information System For Academic Records
MetadataShow full item record
An infonnation system (IS) J_S regarded 8S a sy:-:-:etmhat provides information service; and ]X is useful only if it is accomodated in some activity service In a way that leads to improved activities. Today, infonnation requirements hy modern organisations are vast and complex; the size, comp Lex.ity and specialisa t i.on of an organisation increase the difficulty for decision makers to allocate reSOUTces in an effective and optimal manner. It .i.s well known that for speedy processing of voluminous data,• the computer is demonstrably superior to man; and it is hardly possible to analyse realistic logico-mathematical models and derive varied outputs from them ",ithout the aid of the computer. .... ~..... " - ,> This work is concerned with developing a computer-supported information system to solve problems arising from the use of manual procedures in generating required information from student (academic) records in the faculty of Science, University of Nairobi. The content of the thesis is divided into two parts: PART I deals with general system development ideas. CHAPTER I deals with definitions and concepts that are made use of in later parts of the work- in particular data, information, system} organisation and data base (including elements that characterise it) are treated. Basic steps involved in system development - systems x Analysis, Systems Design, and System lmplementation - are treated in the remaining Chapters of PART I PART II (CHAPTER V to CHAPTER,XII) of the work deals with the system under study. CHAPTER V describes (briefly) examples of typical information systems in a University setting, followed by a treatment of the problems, and objectives of this work. The Chapter-concludes with a brief description of the course Unit System (CUS) which has influenced the system design. CHAPTER VI mentions the relevant input medial devices, followed by a description of the inputs, input documents, and data collection and preparation. CHAPTER VII deals with schemes and criteria for student assessment. Chapter VIII describes the system files - including their maintenance. Relevant output media and devices together with specifications of outputs are dealt with in CHAPTER IX. CHAPTER X gives a system summary by the use of system charts. The system i1as-been programmed in FORTRAN and the program structure and segments appear in CHAPTER XI. The sort phase which is a separate activity is also included. Suggested system operational activities are given in Chapter X!H. . ./ Operations Research techniques turned out to be useful for the computation of the average mark for a candidate's final year assessment. A summary of the relevant technics appears in APPENDIX A. Output lists and reports have been derived from "live" data; Specifications of Faculty course units, and under- graduate student records (year one to year three) - 1978/79 session- xi constituted the inputs in this work: Listings of the computer program and sample outputs appear in Appendix B. The thesis concludes with a list of references.
