Does anyone know a good reference to look into what Object Relational features are available in SQL Server (any version)? I found a really good summery for Oracle but all I can find for SQL Server is information about LINQ to SQL, which is good stuff, but I'm looking for more power in the database like defined types, nested tables, etc.
I know you can use CLR types in SQL Server, and that would be interesting to me too, I just am looking for a good place to read about all the OR features it has.
PS. I'm willing to purchase a book.
