| Abstract: Almost all of the teaching resource data are semi-structured or unstructured. In traditional applications, there are many disadvantages in using RDBMS and le system for storage. This paper analyzes the data structure and application characteristics of teaching resources and the storage mechanism of MongoDB database, and puts forward a storage scheme based on MongoDB + GridFS. Combined with practical cases, the paper summarizes the logical modeling method and important aspects of teaching resource data. |
