In this morning's keynote by Dave Campbell, Dave carried on the message that Pat started yesterday called "Metropolis - Part 2".
The major topics Dave covered can be summarized as follows:
Request/Response. He then talked about each type's characteristics and whether it can be normalized etc. For example, Resource data is normalized and highly concurrent whereas Reference data may not be normalized and is not updated. He then talked about how the different types of data can be represented in SQL storage and the typical formats they take (XML, objects, SQL) when used. Basically, Reference and Request/Response data should be modeled as XML whereas Activity and Resource data can be modeled as objects.
At the end he covered some thoughts on business processes that covered the semantics of tentative operations, cancellation and confirmation, reorderability, and interchangeability of resources and went over a few good tips for how services should be architected to be more loosely coupled.
After the keynote I attended two breakout sessions on Service Oriented Architecture (and a trip to the Microsoft Company Store for some $10 software) which were small groups of 15 architects and a couple Microsoft folks. Very interesting discussion that made me realize that there are more questions than answers in this space at the moment. I walked away with alot more to think about.
One more keynote today and then back to the hotel for more work...
