Introduction to Data Services

I agree with the preliminary definitions and rationale at the beginning of the article, but I'm not so sure about the Development section. In particular, I don't think the "contract-first" approach is promoting reusability of data services. It could be nice if you just intend to consume data services only from a single applications, but it does not sustain an enterprise approach.
This sems to enforce the purely static vision of data services, the one traditionally coming from orchestration, BPM vendors, etc.
The future of MySQL?
I don't know how MySQL will evolve after Oracle acquired Sun.
The Open Database Alliance seems to be an open source community supporting independent branches of MySQL, led by some of the historical contributors.
For sure, many customers will hesitate about MySQL in the coming months before clarification from Oracle and others. Could this create space for another open source database player?
