I general have DAO classes that deal with a single business object / bean and data gateways that deal with multiple results, returning query objects. That way you have the simple rules that DAO = one object, gateway = multiple results (not objects). As always, there are few hard and fast rules and patterns are mostly idealized templates for ways to solve common problems. -- Sean A Corfield -- http://corfield.org/ Got frameworks?
