Data dictionary

The NCIM topology database schema is made up of a set of relational database tables that represent the topology model.

Core tables
Core tables define entities and relationships between them. Core tables do not provide detailed attribute information on the entities.
Core views
The core views group together useful entity data that does not appear in a single table.
Entity attribute tables
Entity attribute tables define attributes for the entities discovered by Network Manager, that is, layer 1, layer 2 and layer 3 entities.
Entity attribute views
Entity attribute views define attributes for the entities discovered by Network Manager, in legacy NCIM topology database format. This enables backward compatibility; for example, SQL queries written to use the legacy NCIM database tables still function because they retrieve data from the entity attribute views.
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).
