Answer 1

SqlDataAdapter

• stores data on your client and updates database as necessary. So it consumes more memory.
• On the other hand you wouldn't need to be connected to your database on insert/delete/update/select command.
• It manages connections internally so you wouldn't have to worry about that.

All good stuff from SqlDataAdapter come at a cost of more memory consumption. It's usually used for systems that need multiple users connected to database.
So I'd say if that's not your situation go for SqlCommand and the connected model.
