摘要
首先分析了移动在线教学系统存在的优势和系统功能,之后着重对该系统所需的数据库进行了逻辑设计和物理实现,通过E-R图进行建模完成了逻辑设计,通过关系型数据库SQL Server完成了物理实现,该系统的设计与实现为移动在线教学系统的开发提供了依据。
This paper analyses the advantages and functions of mobile online teaching system, and the focus is the logical design and physical realization of the database in the system. In logic design, E-R diagram is used to model and relational database SQL Server is used in physical realization. The design and implementation of the system provide a basis for the development of mobile online teaching system.
