Tivoli Directory Integrator is a fantastic and flexible data integration tool that can be used efficiently in implementing the data federation in a CMDB.
IBM's approach for CMDB federation is based on an XML file that complies to an XML schema called Identity Markup Language. TDI is a great and simple way to generate these XML files, as it abstracts all the nuances of the XML file into CI types and attributes. This video shows how easy it's to create this IDML file.
The power of TDI thou doesn't come from the IDML Connector, but it comes from the plethora of available connectors (JDBC, JMS, Notes DB, Web Service, HTTP, to name a few) and the flexibility it provides to connect many data sources without the need to write a single line of code. Want to create an IDML with just the data that changed since last time? You got it. In TDI, it's just a few click away, just the Delta capability.
Another interesting aspect is that there are other TDI connectors available in the CMDB / Service Management space: the Maximo Generic Connector let us interface with CCMDB without having to generate an IDML file, but going through Tivoli Integration Framework. The TADDM Connector lets you create (and retrieve) CI from TADDM, which will be imported into CCMDB.
