If want to know about BO design and what you're talking about above, then
get the book, download the CSLA framework put it together, download the
Tracker project and make it work with the CSLA Framework. You should forget
about implementing the CSLA Framework, but rather, how are the BO objects
being used, and who are those basic BO(s) and their roles. It going to show
you table driven roles, rolelists, objectstate etc, ect. You pull out of
that book what you need and you run with it in making your own BO(s). You
won't regret getting the book. It's taught me a lot, and I always use some
aspect of what I have leaned from that book in physical N-Tier or logical
tier design with using Web, desktop. Concole NT Service solutions using
..Net.. The book teaches you about presist themself BO(s), but you can
eactact that data persit loging into a BL/DAL concept as well, which I have
done.

You may want to look at DDD concepts. The book I use is the C# one, but
there are others. You can maaybe find one for VB.

Everything I have learned form the Head First book I have implemented in
..Net application design. OOp is OOp whether it be Java or .Net.
