Data query function

14.1 Functional Overview

There are query synchronization data wrapper methods in each model class. Only the encapsulated method query has detailed data, while the data queried by the custom query method has no detailed data, and the detailed data needs to be converted and assigned by itself. Database operations are recommended not to delete database data, but only to insert or update data. The current data can only be queried after the synchronization is completed, and the unsynchronized data is still in the bracelet。
