Perhaps you should have taken more than a first glance. For example, here:

"Core Data is not a relational database or a relational database
management system (RDBMS)."
This is unrelated to the problem. Mike, I think you are using a straw man argument - or you totally misunderstood me.

Why would you think I had ever designed a database application or
framework? All I know is, CoreData is *not* a database framework, so
your whining about how it fails some fundamental requirement for
database frameworks makes no sense.
I think you misunderstood me. Core Data could be a very useful *part* of a database application framework. But it is not, because it apparently lacks the ability to interface to other related parts of a database application framework (ORM, data access layer, storage management) - at least this is what I conclude from this discussion.


Again, to make this clear: I don't claim that Core Data should implement all these layers of a database application framework (or even a RDBMS). And honestly, it should not! Rather it should provide a means to interface with them.


And using your car example: having tires is certainly useful. But they become even more useful if you can mount them on your car. ;)
