| The credit hour system (CHS), characterized by course selection, is an integrated teaching and management system to evaluate the quality and quantity of student learning based on Grade point average and credits. However, traditionally trivial educational administration system (EAS) dependent on the academic year system does not match the modern CHS model in the schools. Here, to comply with the human-oriented education policies and to maximally extricate the educational administrator from the trivial daily affairs, we design and implement an integrated, informational and practical EAS characterized by CHS (named iEAS- CHS), main contents of this thesis are as follow:1. The developing background of EAS- CHS is introduced, the situation and the significance of information system of EAS are elucidated, and the structure and the main function of the iEAS- CHS are put forward.2. The characteristics of CHS and the data flow chart and the functional hierarch of the system are analyzed, the requirements of course selection and intelligent course arrangement in CHS are discussed, and three key parts (course plan, course arrangement and course selection) in this system are designed in detail.3. An overall design of the system and the system's network topologic structure are proposed. The structure of the system based on the C/S and B/S and the database model in the system are designed in detail, a series of security measure for database security are put forward and adopted.4. System functional modules for different users including educational administrator, department administrator, general user and student are analyzed and designed, analyzing and exampling the procedure of the rules and functions of the course selection are analyzed, and some examples are given. The functional realization between electronic automatic course arrangement and manual course adjustment are analyzed by some examples.5. The implemented system has been summarized and the potential improvements are put forward. |
