Oh I'm sorry, I never mean to exclude anyone from answering any of my questions. Just the writing sometimes seems more natural to me if directed towards a single person. Thank you for your input.

I'm less curious about specific language designs and more curious about I guess architecture and library issues. For example Rel incorporates a complete DBMS implementation. And the most recent experience I had with a DBMS (DB2) was using the usual client/server architecture to submit queries while most of the analytical computation was actually done in Java.

All that seems a little to heavy for what I want to do; that is incorporate relational concepts and thinking into my tools and simulations. I'm looking for a way to develop stand-alone apps where the relational code operates directly on the data structures used by the rest of the language. Something like the C# example linked before or the Tutorial D examples some have posted in c.d.t before. However, the "compiler" should ultimately include only the DBMS functionality needed to correctly implement the code rather than using a complete black-box DBMS server.

For example, how much relational functionality could one incorporate into say a C++ library with relation classes, RA functions, etc without being a front-end for a full-blown DBMS back-end? Anyone know of any such libraries?

Does it even make sense to talk about a relational language compiler that does not link to a full-blown DBMS?

I think I'm failing to describe such needs using correct relational and/or DBMS terminology. Am I making any sense?
