Teaching resources are the premise and foundation of developing online education. With the gradual expansion of online education, online teaching resources are becoming more and more abundant. Effective management of teaching resources has become the key to the development of online education, providing efficient storage management for all kinds of learning content objects, convenient access for all kinds of users, and evaluation and analysis of resource access effect for teaching managers.

So as to improve the utilization rate of teaching resources and promote teaching resources to better serve the actual teaching system. The network teaching resource database system is mainly composed of teacher resource database, student resource database, enterprise resource database and network resource. It consists of seven parts: resource management system, resource query system, teacher role application interface and student role application interface.

The data in the public resource library is divided into three classes of courseware because of its granularity and composition. The public resource pool has the following characteristics: the resources in the public resource pool are managed by the system, and teachers have no right to upload teaching resources directly to the database. Teachers have their own resource pool, and upload resources from personal resource pool to public resource pool.

It needs to be strictly audited by the management system, but the teaching resources in the public resource pool can be downloaded to the personal resource pool. The structure of the resource pool not only ensures the safety and unity of teaching resources in the public resource pool, but also takes into account the management of teachers' personalized resources. Teachers can organize the basic resources in the public resource pool at will according to the teaching needs.

And release the results to students in the form of electronic lesson plans, or use integrated units to complete specific teaching activities, or directly release various courseware in the courseware library to students. Students can only use the specified resources.

According to the actual function, the public resource library is divided into the following sub-libraries: courseware library, microteaching unit library, case library, test library, frequently asked questions library, terminology library, reference library, website library, shared software library and basic library.
