I read a book about  ASP.NET that talk about Entity Framework and here they 
use the Northwind database as an example.

What I find strange is the relationship between Customer and Order.
The book print the relationship between Customer and Order like this
!--------------!                           !-------------------!
!   Customer   ! 0.1 ................ * !           Order       !
!--------------!                           !-------------------!
I found this strange because it means you can have orders without a 
Customer.
