AFAIK the basic code goes back to Berkeley days. Elein might possibly
remember something about it, but no one else that's on the project now
was involved then. The right place to look would be in the Berkeley
project's publications:
http://db.cs.berkeley.edu//papers/
I agree with Neil's point that it's a spiritual descendant of System R
and there's plenty of material about that in the general database
literature.
