-You can use each data source to create ai data sets for that data source. Tables from one or more different databases can be placed in an ai dataset.
-You can also right-click all tables on the Tables node under each database to add a specified table to the ai dataset.

-You can edit the table by double-clicking it within the ai dataset. If your business cannot modify the table name or table comment, you can modify the table name and comment as well as the field name and comment information here, so that AI can better understand your table structure and field information.
-This will greatly improve the accuracy of ai generation.
