基于Web服务及XFire，运用Struts，EJB等关键技术，设计并实现了一个松耦合的教师管理系统解决方案。通过EJB数据模块实现对数据操作的封装，通过Web服务技术实现业务逻辑对EJB数据模块的访问，使得它们不依赖于彼此的实现技术和运行环境，具有更好的灵活性和可扩展性；同时，也考虑了教师管理系统与教育信息化项目中其他系统交互的问题。

Based on Web services and XFire, using Struts and EJB technologies, design and implement a loosely-coupled Teacher Management System. Encapsulate data operations through EJB data module and manage to access the EJB data module through Web services technology, which makes them independent with the run-time environment and programming technologies of each other, and offers better flexibility and extensibility. And the research also leads consideration about the communication between Teacher Management System and other systems of Teaching Resource Plan Project.
