Obviously, I only know what you've told us about your data, but 20-100
queries?  That doesn't sound right.  I know that I have often thought
that my data and its structure were complex, but then ended up with a
fairly straightforward table structure and pretty small queries.  With
the right set of tables and a strategically placed view or two, IMO you
shouldn't need that many queries.  As Paul noted, RDBMSes are well-
studied and well-understood; they are also extremely powerful when used
to their potential.
