SOA as SQL

It's an interesting idea: using a SQL-like query language for your service API.

The 'purpose' behind many service APIs is to store and retrieve data on a particular subject remotely. In a lot of ways, SQL seems like a good metaphor for doing so. It allows you to cherry-pick the data you're interested in, join it with other data, etc.

It'll be interesting to see if this is an idea that gains any traction.
