Today I started working with Analysis Management Objects (AMO) which is a library of classes that users work with to create and manage Analysis Services objects.  Although DSO 9.0 (Decision Support Objects) is available in Analysis Services 2005, it is being deprecated and developers are encouraged to use AMO instead of DSO in the future.  So far, I've been highly impressed with AMO.  Hopefully I can get a few scripts out in the next week or so.
