 |API|Description|
 |:------|:------|
-|onInitialized|Called during ability initialization to initialize the relational database (RDB).|
-|update|Updates data in the database.|
-|query|Queries data in the database.|
-|delete|Deletes one or more data records from the database.|
-|normalizeUri|Normalizes the URI. A normalized URI applies to cross-device use, persistence, backup, and restore. When the context changes, it ensures that the same data item can be referenced.|
-|batchInsert|Inserts multiple data records into the database.|
-|denormalizeUri|Converts a normalized URI generated by **normalizeUri** into a denormalized URI.|
-|insert|Inserts a data record into the database.|
-|openFile|Opens a file.|
-|getFileTypes|Obtains the MIME type of a file.|
