Managing the common data model

The Common Data Model (CDM) of the BMC Helix CMDB unifies the representation of configuration data. It stores information about the most common configuration items, such as hardware, software, and services. The CDM provides a mechanism for linking CI information to provide a complete view of all elements of an IT environment and the manner in which these CIs affect each other.
