摘要
针对传统课堂教学不能很好地延伸和拓展,学生不能灵活地掌握学习主动权,学生学习和教师教学缺乏有效交流平台等问题,将Browser/Server三层体系结构、Servlet、JDBC技术应用于远程在线教育系统中。研究了系统实现的技术原理,系统功能需求,从系统用例图、时序图、协作图、状态图方面进行了系统UML建模、完成了数据流图、数据字典、系统流程和数据库设计,最后对系统进行了黑盒测试,测试结果达到了预期效果。
In view of the traditional classroom teaching can not be very good extension and expansion, the student cannot be flexible learning initiative, effective communication platform issues such as the lack of students＇ learning and teachers＇ teaching, the three level architecture of Browser/Server, Servlet, JDBC technology is applied to the remote online education system. This paper presented the technology principle of the system, the system functional requirements, the system use case diagram, sequence diagram, collaboration diagram, state diagram for system modeling in UML, completed the data flow diagram, data dictionary, system process and the database design. The system has the final black box testing, the test results achieve the desired effect.
