Here's a Tech-Ed Microsoft Powerpoint off the MSDN site. What is UDM? UDM is a term for the "Unified Dimensional Model" in Yukon Analysis Services, or a common interface for both relational and mdb sources for use with reporting applications.

Not a whole lot of detail on how it works, but some high-level explanation of supposed benefits. A few screenshots of the BI Workbench in Yukon too.
