title: SqlCommand or SqlDataAdapter?
body: <p>I'm creating something like a small cashier application that keeps record for the clients, employees, services, sales, and appointments. I'm using windows forms, and within that DataGrids. I've created the database that I'm going to be using for the application. I want to know if I should use SqlCommand-SqlDataReader or SqlDataAdapter-DataSet instead. Which approach is better?</p>
