  Greetings. I am a IT Engineering student from spain.  I'm learnin Design Patters at School with Java, but I work with .NET. Is there in .NET a Object Persistance Framework, or something similar, so I don`t have to do use SQL .  I mean, if I design my aplication purely Object-Orientated, there is a point that I should design classes for data access (or I could implement the data access in the classes I already have).  But if I had a this Framework, the only thing I must do is configure it, describing the database and that's it.  In java there is something called Hibernate.
