Hmm, it looks as though you're right. However, in the next sentence he
asked "Is this advantage better or worse than a triple design?" Since I
don't particularly separate OLAP from relational I thought it must be a
OLAP vs. triple design question.  Then again, maybe it's just that I
find the latter a much more interesting question to ponder...
