Common Data Model views

The Common Data Model (CDM) is an information model that provides consistent definitions for managed resources, business systems and processes, and other data, and the relationships between those elements. CDM is based on the unified modeling language (UML).

The IBM® Common Data Model (CDM) overlay schema enables Network Manager to expose a subset of its data in a CDM-like relational representation corresponding to aspects of the CDM Computer System, Networking, Operating System, and Physical sub-models. The CDM schema complements the NCIM topology database by providing tables to allow the storage of extra CDM attributes.

The CDM views exposed by Network Manager are defined using existing NCIM database tables and attributes.

CDM views

The CDM views are described below. For each CDM view the corresponding row lists the tables and views mapped to by the CDM view.
