This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
Is there a persistance framework out there that's more or less completely transparent? Yes, Hibernate, but not quite. It beats out most other technologies in terms of not being seen, but it's not fully transparent. I don't mind the intrusion of an identifier and all that, that's not what I'm getting at.
1:X | 2:Model | 3 ersistance
In Hibernate, as with everything else it seems, the objects really reside on #3. The model that you work with is not the 'real' model, and your code knows this. True transarency, to me, would be the model classes, some special collection of them (that's all, nothing more), and forcefully restarting will yield the model objects just as they were.
Here's a naive idea: say you have a new Cat(), other cats, and a big special collection of cats. allCats.add(newCat) (or someCat.setParent(newCat)) will persist said cat, and as you'd expect, losing the cat as a referance and then removing it from the collection will mean the cat is no more.
Does something like this exist, and what are your thoughts on the matter?
