SYS_TABLES
This table lists all the system tables.
There are no restrictions for viewing the system tables, which means even users with no access rights can view them. However, specific users are restricted from viewing the user table information. Owners are restricted to viewing user tables they have created and users can only view tables to which they have INSERT, UPDATE, DELETE, or SELECT access. Users are restricted from viewing any user tables if they have no access rights. No restrictions apply to DBAs.
