With the advent of LINQ to SQL, there is a new way.  First, create your objects, and then bind directly to a LINQ query. Note however that when binding to a LINQ query, the information is read-only. If you want a read-write binding to multiple database tables, a table adapter wired up to stored procedures for SELECT, INSERT, UPDATE, and DELETE commands is still the best way to accomplish this.
