Planning to use federated data
Federated data is data stored outside BMC Configuration Management Database (BMC CMDB) but linked to configuration items (CIs) so that it is accessible through BMC CMDB. The most common types of federated data are related information and detailed attributes.
Related information is information about a CI that does not itself qualify as a CI and therefore should not be stored in a CMDB. Detailed attributes are attributes of CIs stored in BMC CMDB, but they are attributes that are not important enough to track at the level of a CMDB.
In BMC CMDB, not only can you view federated data, you can retrieve that data for use by a consuming application as if it were part of BMC CMDB. This feature enables you to access outside data from central CMDB repository and lets you use your existing data store infrastructure.
The following figure illustrates both types for a BMC_ComputerSystem instance named Computer A. The instance can be linked to incident records about Computer A, which are related information, and also linked to discovered attributes of Computer A that were not imported into BMC CMDB.
Federation Manager plugins and adapters provide the mechanism to connect the master BMC Configuration Management Database (BMC CMDB) to external sources of data, federating data from different types of repositories. The following figure illustrates the concept of federation between BMC CMDB and a federated Oracle database.
