I've had very good luck with Torque, I'm maintaining code for some
fairly hairy insurance-related applications (can you say lots and lots
of joins?), and Torque has made writing the persistence layer a piece of
cake.  It used to be the thing that gave me the most tsuris, now it's
one of the easiest tasks.

As to seperation of beans and db, I've always believed you can take
abstraction to far.  Torque does a good job of hidding all the
db-specific details inside auto-generated classes, leaving your
business-specific code in files that are db-independent (the Foo classes
as opposed to the BaseFoo classes).
