... yes, and if you are going to be pedantic, please be somehow consistent with the docs:
> Core Data provides an infrastructure for change management and for saving objects to and retrieving them from storage. It can use SQLite as one of its persistent store types. *It is not, though, in and of itself a database. * (To emphasize this point: you could for example use just an in-memory store in your application. You could use Core Data for change tracking and management, but never actually save any data in a file.) http://developer.apple.com/library/mac/#documentation/cocoa/Conceptual/CoreData/Articles/cdTechnologyOverview.html#//apple_ref/doc/uid/TP40009296-SW1 On Sat, Jun 22, 2013 at 1:26 PM, Timothy Reaves < trea...@silverfieldstech.com> wrote: > Yes, CoreData is a database, and it does do ORM.
