DAO used to be on the SCWCD but it was removed because it's actually in the business tier.
Value Object was changed to Transfer Object for the exam because, well, what the exam described was really a Transfer Object and not a Value Object. The two terms get used interchangeably a lot. But a Value Object really only holds (by Martin Fowler's description in the book UML Distilled) one value. A Date object would be a Value Object; it has one value. A Transfer Object, on the other hand, is meant to hold multiple objects/values to pass them all together in a method's return type so you don't have to call a separate method for every value you need returned.
