Looks like you need something like Entity Framework code first. Start here: http://www.codeproject.com/Articles/318010/Entity-Framework-Code-First-Let-s-Try-It, than here: http://msdn.microsoft.com/en-us/data/ef.aspx

In OO there are many important types of relationships to name a few
- aggregation : a class refers to another one, but the class has no ownership of the referred class
- composition : a class refers to anothr one, and has ownership of the referred class
- inheritance : this is a "is a" relationship.

Another aspect is the cardinality. If a class contains for instance an array of another class the cardinality is * or max dimention of the array.

But this is all pretty basic stuff. If you don't know all this you should really read a good book about OO programming in general. Perhaps even UML because UML is all about relationships between classes both statically and dynamically.

This is really a basic question that you could finmd the answer to by looking in Microsoft's Visual Studio manual:

So I guess its back to basics :)
