J2EE框架下教学辅助系统模型的设计与实现

在设计和开发高等学校教学辅助系统时，教师、学生、班级、课程等实体的对应关系是一个难点。提出了一个新的系统模型，能灵活地在不同功能模块里处理上述对应关系，能在很大程度上满足系统扩容的灵活性和二次开发的重用性。适用于设计教学辅助系统时的模型选择。同时，给出了在该模型下的两个应用范例。

Design and realization of a model for teaching system based on J2EE

The relative relationships among the entities of teachers, students,classes and courses are a difficult point on the process of designing and developing a teaching assistant. As far as this issue was concerned,the author proposed a new system model. The model was capable of dealing with the above corresponding relationships in different modules effectively, and considerably satisfing the flexibility of the system extension and the reuse of the second-time development. It is suitable for the model choices in designing the teaching assistant systems. The article elaborated two types of implementation of the model.
