first off, thanks for the links. Secondly, > That doesn't really change the equation. You still either have to (1) choose your DBMS's query language to write your application server (like today) or (2) use one language to construct queries in another (like today). I don't know if you're misunderstanding me, or I'm misunderstanding you. prolog is a query language. The logical programming paradigm is that a program is a "list of facts" and you run the program by "querying" the state of the world. The only piece missing is making the fact storage engine scalable/robust/production ready. Or.. alternatively, there's the Eve[1] project which starts off with prolog to make a hypercard like environment with a built in data storage layer. Its aim is less production ready apps and more developer ergonomics. [1]: ( http://witheve.com http://witheve.com )
