There is not a sophisticated free solution available on the web (I've
searched tons). The basic model is the Northwind. But, for a real life
sophisticated model, there is one book out there that has become to be known
the authority on database modeling of all sorts - check out this book:

http://www.amazon.com/exec/obidos/AS...owertechcanada

This book saves tons of time when developing any database project as you can
combine it into your project very easily.

It has sample models for Party's (relationships), Contacts, Orders,
Shipments, Invoices, Accounting, Employees, Human Resources, etc. The models
in this book are complex models that are implementable by all sorts of
business - even Fortune 500 businesses. Volume 2 of the same book has models
for specific industries such as Financial Services, Professional Services,
E-commerce, Manufacturing, Health Care, Insurance, Travel,
Telecommunications.
