Hi Mike:
I too looked at the Data Model book and would agree with your 
interpretation from the book.

Since my opinions seem to inflame David to no end, I think I'll just 
stop trying to help out here and wish everyone best of luck in 
understanding how this all fits together.

Should anyone care for more of my opinions on this or any matter 
concerning OFBiz (or the coming elections :-), please feel free to 
contact me via the myofbiz.com website. That is what it is there 
for...to spread OFBiz information - real or imaginary.

Best Regards
Ruth Hoffman
