Metadata catalog

The information that you generate from the Classic Data Architect is stored in metadata catalogs. A metadata catalog is a set of relational tables that contain information about how to convert data from non-relational to relational formats. The data server accesses the information stored in these catalogs.

Metadata catalogs emulate relational database catalogs. The metadata defines business-oriented relational mappings.

You can use the catalog initialization and maintenance utility to create or perform operations on a metadata catalog.

In addition, the metadata utility accepts DDL that is generated from the Classic Data Architect. The metadata utility must successfully connect to a data server before running any DDL statements. The utility updates the system catalogs with the contents of the DDL statements.
