The semantics of sql and prolog are the same, so in one sense it's everywhere - relational databases. Prolog specifically is not commonplace because historically the gui's have been written with OO and then the web came and frontend was stateless (html pages sent to browser). As gwt-style single page apps become popular again, hopefully this time prolog will replace OO.

I'm rather uninitiated into all this. What's your basis for claiming the semantics are the same? Isn't backtracking present in Prolog and absent in SQL?

There's a good stackoverflow answer on that http://stackoverflow.com/questions/2117651/difference-betwee...

That looks super. Thank you!
