Other details:
In IMS systems that use DBD libraries, use the Database Description Generation (DBDGEN) utility to define a database so that it can be used by an application program
This utility might not be used in IMS systems that manage runtime application control blocks by using the catalog.
A database description (DBD) is a DL/I control block containing all of the database information needed by an application program.
You create a database description (DBD) by coding special macro instructions. These macros become the input to the DBDGEN utility.
You can use only one physical DBD to describe each physical database; otherwise, a user abend, such as 0850, 0852, or 0853 occurs. At execution time, DL/I uses the DBD to create a set of internal control blocks.
The DBDGEN utility defines each DBD with the following database information:
Segment types
Physical and logical relationships between segment types
Database organization and access method
Physical characteristics of the database
Define the name and data options of selected exit routines
Metadata that describes the database and the data stored in the database
