Research And Analysis On The Information System Of Elective Course Selection In Colleges And Universities

In this thesis, we take students online course management information system of Guizhou Normal University as an example, by making a brief analysis for research background, meaning and purpose, as well as the progress and application of research in the field of comparable systems. We believe that the existing offline paper-based management mode is inefficient, complex, time-consuming, and the results are not easy to save and share. Then, we propose that it is a effective way to fix this problem by building an online course management information system with the application of information technology.Therefore, in this paper, we use object-oriented analysis and related technical methods, UML (Unified Modeling Language) and Microsoft Visio2013 for the analysis of business requirements, functional requirements, data flow analysis and detailed aspects that involved in the online course management information system. In business requirements analysis, system operational issues related to the research subject and the original business process analysis were discussed. We propose that the online course management information system related control rules, business process control, and describe of the relevant flow Chart. In functional analysis, based on business requirements analysis, we extract the overall system use case and sub-cases, and then gives the case diagrams, including:basic data management, course management, pre-management, positive selection management, election management and system management sub-use case diagram and detailed description, and based on the sub-use case, given management package diagram and detailed description of each module. In the data analysis, based on results of requirements analysis and functional analysis. The online course management information system involves a different of interface classes, control classes, entity classes design, and the thumbnail showing the relationship between the class and a detailed description of them, and completed system design background database table structure. Finally, research and analysis work done by the author in the online course management information systems are briefly summarized and clarified the direction of future research work and plans.The research and analysis work of this thesis will provide important supports for coding, testing, management and maintenance of the online course management information system. There are also some reference value to the research work for scholars in relative research field.
