DIM Classes
The Global Unique Identifiers for the DIM Class Descriptions and Relationship Descriptions are defined in the header file dbaim.h. This file also contains the constants for the DIM Property Names and Relative Property IDs.
A Teradata Database system is initially loaded into the MDS repository using the metaload program. Meta data objects loaded into the DIM are referred to as DIM objects and are readable by any MDS User with the appropriate read permission.
The information needed to read the values of the properties of objects in the DIM classes is contained in the following tables.
