Does DataAdapter use facade pattern or Adapter pattern.

Question

When I see Update(), Fill() methods of DataAdapter object, I always think whether DataAdapter uses Facade Pattern?

It looks like behind the scenes it will create Command object, Connection object and execute it for us.

Or DataAdapter uses Adapter Pattern because it is adapter between Dataset and Command object, Connection object?

Answer 1

Not everything is a GoF design pattern.

Answer 2

I think you could perhaps think of it like the Repository pattern, just that it focuses on data connections. Its not really an adapter because its not facilitating a communication mechanism between command and dataset - its actually manipulating and creating its own commands for its own purposes.
