Just some random thoughts I had while reading this thread...

I'm curious as to why query language development got hung up on SQL.
I've read a little bit about Tutorial D.  Is SQL simply
another example of pre-mature standardization?

What would a Ruby interface to the underlying database engine (indexed
tables) look like?  Could it get closer to Tutorial D by bypassing the
standard technique of 'marshaling' requests into SQL statements?  Is
the impedance mismatch between Ruby (or any other OO language) and
Codd's relational algebra too great to cross smoothly?
