Thanks Gregg.   I appreciate your insight.   I'd agree with you re:
understanding the pro's and con's of various models.  I also understand
the need for not holdnig database connections.   What had me scratching my
head is the techniques for non-db (ie. business) components.  I sort of
come to OO programming from a "theory" perspective, where VB's
implementation is one I actually work with.  To some degree, VB is asking
me to give up on some (more) of the OO theory.  Programming for MTS/Com+
is such a large departure from my understanding of OOP, that I felt I was
missing something.   I think I'm on-board now.  I'll "go with the flow".
Thanks.
