Managing external data stores using Federation Manager
The CMDB stores the most important information about your configuration items (CIs) that you require for the smooth functioning of your ITIL processes. Any additional information about the CIs that you require that is not critical can be stored externally and made accessible to the CMDB using various methods. Storing data externally outside the CMDB and acessing them using data stores is called federation and this helps maintain optimum performance of the CMDB.
A data store can represent multiple sources of external data. For example, a data store can represent data from databases (retrieval type) or launch in context links. You can use the Federation Manager to federate external data through a data store, making that data available to view and query with BMC Configuration Management Database (BMC CMDB) tools, such as the CMDB Explorer.
Depending on the method of federation, you can configure federated definitions in the following ways:
|Launch method: Access a particular type of federated data from a specified federated product.|
|Retrieval method: Define a federated data class in the BMC CMDB data model that represent sets of information about the external sources of data (such as a tables on a databases).|
