I think DAO is closer to Adapter (anyway, it's more strutural than creational). Value Object is also structural in nature, so in some cases it could be Composite, in most cases it's just a bean, nothing else. I do not think that Memento's usage strategy will work for VOs.

DAO = Bridge + Adapter
The Adapter part is in the implementator of the Bridge.
Often created by Abstract Factory or Factory Method.
