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. //Tony
