The IBM IMS catalog
This chapter provides a description of the IBM IMS catalog and the way it can be used to expand and consolidate the information about IMS databases and their metadata.
The IMS catalog is an optional system database (available since IMS 12) that stores metadata about your databases and applications. Its comprehensive view of IMS database metadata, fully managed by IMS, allows IMS to participate in solutions that require the exchange of metadata. A type of solution that requires such an exchange is business impact analysis.
