To explore this in any depth, let's clarify what FP is. The function is considered as a data? I fail to see why this idea is significant. Care to support it with an example?

Well, we are not talking completenes, are we? Certainly, in RA we can't express certain things that even primitive procedural language can do, yet we agree that algebraic approach is a good idea.

I'm not certain where this observation leads to. Combined with an idea that function composition is nothing more than a relational join, the intuition might be that an extension of the relational model don't necessarily require functional programming ideas. Received on Thu Mar 06 2008 - 22:45:22 CET
