Don,
I''m glad there are still folks that think about the modeling and design
essential to quality system development.
Of course, I am a bit biased in this respect given that it is a large part of
what I do in my day to day work !!!
If you are looking for a good source of models then I would suggest
"Enterprise Patterns and MDA : Building Better Software with Archetype
Patterns and UML" by Jim Arlow and Ila Neustadt (Addison-Wesley, ISBN
0-321-11230-X). It covers the major "archetypal patterns" which you
can
modify to you own particular requirements. Among those you might be
interested in from a "store" viewpoint are Customer, Product,
Inventory,
Order, Quantity and Money. There is a sample chapter (on "Money")
available
at -

I hope this isn''t too rigorous a work for you.
Ironically, I did a data model for an online record store a number of years
ago. And one of my current customers is in the online music business too.
So I''m fairly familiar with the challenges you may face : especially
when
relating music to genres and subgenres !
