ADO .NET provides many rich features that can be used to retrieve and display data in a number of ways, but even given such flexibility, sometimes developers find themselves repeating the same code again and again. For example, every data-driven application requires access to a database. You need to write code to connect to the database, open a connection, execute dynamic SQL or stored procedures, retrieve the results, and close the connection. In other words, this is "plumbing" code that you will be forced to write in almost any application you develop, even though it doesn't add any value to the core business users.
