Domain definitions enable ranges of values to be defined and designated for table columns.
Each value range definition has a name that is unique within the overall database system.
If a domain was defined without an owner, the catalog sections (part catalogs) are searched in the following order to locate the specified value range:
1. Catalog part of the current user
2. Catalog part of the DBA who created the current user
3. Catalog part of the SYSDBA
