The BMC Atrium Configuration Management Database (BMC Atrium CMDB) is a multi-component database that enables applications to store and share data. Service model developers and administrators use the BMC Atrium CMDB Configuration Console and BMC Atrium CMDB Class manager APIs to build and modify the Common Data Model (CDM).
With the BMC Atrium CMDB, you can divide your configuration data into partitions called datasets, each containing configuration items (CIs) and relationships for a given purpose. This makes it possible for the same component or relationship instances to exist in more than one dataset.
Datasets provide a mechanism for storing raw data from multiple resources in discrete locations. Then, the reconciliation process takes that data and merges it appropriately to create a composite set of unique data instances that includes information from each source, based on what each source is proficient at obtaining. The ability to capture the raw data from various sources and reconcile it to a controlled dataset enables the interaction between various automation tools.
