Datamodule in VB.NET

I would like to have a Delphi like datamodule for my VB.NET programs.
The nice thing about a datamodule is that it provides isolation for
the database connection and it allows a program to switch databases
easily. Is there such a thing for VB.NET.

In my VB6 programs I use a GetCn procedure that gets parameters from a
config file. That is a more simple way of doing it but useful. I just
wonder how to design a VB.NET program so that I can easily switch
between databases. Thanks for any help.
