Brief introduction:

• Traditional relationship types (orm:object-relational Mapper), MongoDB (Odm:object Document Mapper);
• MongoDB is a document-oriented, Schme-independent database that can store any type of document data in a collection;
• MongoDB can treat data as a document, and the document can be any depth;
• When data is stored, these documents are stored in very close to JSON format;
• The data type of the document data can be mixed, and node. JS obtains the same type and storage type as it does when storing the document data;
