Yeah. I had a few thoughts about doing it in SQL, but they all involved
unanchored text searches ... with consequent super-sucky performance.

Well, your company is hardly the first to act penny-wise and thousand$-foolish
in terms of expensing a project; most of my $200/hour DBA consulting gigs
come from companies whose database was royally screwed up for 6months- 1 year
and they finally got tired of it.

There are ways around this that don't involve denormalization of the central
data tables. "Cache tables" for one, with deferred processing for permanent
storage.

OK, I'll try when I can.

Please also check out the book review list. Particularly, Fabian Pascal's
book is a must for you.
