The network teaching system provides an opportunity for new educational methods and expands educational functions in an all-round way. Network teaching breaks the traditional classroom teaching mode, breaks through the effective communication and exchange that cannot be implemented in distance education. Database design is an important work in software development. In the process of network teaching system development, from the perspective of user needs, the conceptual structure design and logical structure design of the database are carried out according to the standardized method. The result of conceptual structure design is represented by E-R diagram, which is composed of 5 entities and 5 links between them; the logical structure design is based on Oracle database management system, and the conceptual structure model is transformed into a specific table structure. Improve data storage efficiency and access speed by optimizing design results.
