categorizes the database objects into the following logical groups:
A source database contains the user data in the User Source Tables (UST).
can access the USTs by using a user ID that has select privilege on the USTs.
creates fuzzy indexes on the USTs. Use triggers to synchronize the indexes with the UST updates.

The user ID must have the privilege to create triggers on the USTs.
A target database contains Identity Tables (IDT) and Identity Indexes (IDX).
creates and updates the identity tables and identity indexes by using a user ID that has create privileges.
If you want the IDTs and IDXs to remain in synchronization with the USTs,
