My understanding is that for all the fancy talk, Rushmore essentially boils
down to the use of bitmap indexes.
InterBase (and likely many other SQL engines) have used bitmap index
techniques for quite some time. I'd expect it to be a fairly standard query
optimisation technique.
It just took a while for the PC database/dBase world to get their hands on
engines that used it.
TTFN,
Paul.
