            var datastore = new DataStore("d_department");

            // Calls SetDataContext to set the data context.
            datastore.SetDataContext(_context);

            // Retrieves rows from the database for datastore.
            datastore.Retrieve();

            Console.WriteLine("After Retrieve, Rowcount: {0}",
