DOMAIN is the Windows-based DBA tool of ADABAS which provides information about the static and dynamic properties of the defined database objects. It offers all ADABAS DDL facilities for the creation of new database objects and the maintenance of the existing database objects in a menu-driven way. Essentially, the following database objects can be administered with DOMAIN (create, update, show, drop, comment):
- Tables
- Views
- Synonyms
- Domains
- Indexes
- Triggers
- DB procedures
- DB functions
- Users
- Privileges
Access to DOMAIN information is also valuable for application programmers because they can inform themselves very easily about the structure and properties of the database objects they work on.
As for all database objects, usage information is implicitly maintained by ADABAS; DOMAIN represents the data dictionary associated with ADABAS. For example, it can be determined very easily which application programs use a certain table or column. This usage information is of greatest advantage for the maintenance of the database objects because the implications of modifications can only be assessed on the basis of this information.
