Accessing external data through CMDB by using Federation
You can define a data store to represent a source of external data. For example, a data store can represent data from databases (retrieval type) or cross-launch links. You can use 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 what kind of data you want to configure to be available in the BMC CMDB, you can use either the cross-launch or the retrieval method.
