statistical use of various database types in Delphi

Was there anywhere published some
kind of statistics of various database types
used by Delphi developers ?

For example:

dBase 40 % of desktop database applications in Delphi
paradox 30 %
fox  15 %
other 15 %

I myself use foxpro 2.5 tables/BDE4.0 and seem to me
that Borland takes fox tables like some {*word*118}
thing - is paradox better supported in context
of stabILITY and BUG FIXES ?

I think that database type to use is an
strategic decision to make !
