While scanning the exam objects for 1.3 and 1.4, I notice that two patterns from 1.3 were dropped from 1.4 - value object and data access object. Are these pattern obsolete?

Howdy -- we felt that DAO (Data Access Object) just wasn't specific to Servlets, so we dropped it from this exam. It''s definitely not obsolete!
But Value Object is now something that Sun calls the Transfer Object, so... it's still valid and still there, just using a different name
[edited by Kathy because I first called it "Data Transfer Object", not "Transfer Object". Data Transfer Object, Transfer Object, and Value Objects are all names for the same pattern... don't get me started ] [ October 06, 2004: Message edited by: Kathy Sierra ]
