A database environment always consists of at least one data dictionary and one database. A data dictionary contains definitions and information about the input data that CA Culprit uses at run time. A database contains the input data.
An installation can also establish alternate dictionaries to maintain information specific to a particular application or group of applications; these dictionaries usually share some information with the startup dictionary.
Similarly, company data can be divided among several databases; for example, an employee database, a production database, and a test database. A test database usually contains the same type of information as a production database but contains less data. If the subschemas of the test database and the production database are identical, application programs do not have to modify the name of the subschema to access one or the other database; the programmer merely has to identify the database.
DATABASE Parameter
The DATABASE parameter is an optional parameter that allows users to access a particular data dictionary and to retrieve data from a particular database in a multiple data dictionary/database environment.
Users can also access another DC/UCF system when using the distributed database system. Each DC/UCF system is a node in the DDS network. Each node controls one or more data dictionaries or databases.
Note: For more information about distributed database environments, see the CA IDMS DDS Design and Operations Guide.
