John,

The second project I downloaded is a bit too hard for me. I really wanted the one associated with the article since this is also very close to the application I have to develop (Orders system).

May be you have this one somewhere? Otherwise I'm sort of stack again. I created a Biz Object project and Data Access Project in the main solution, but what I should do next is not clear.
