Core Data

MacOs X Data Store. The technically correct way to describe Core Data is as an object-graph management and persistence framework. In down-to-earth terms, this means that Core Data organizes the application's model layer into a set of defined In-Memory data objects. Core Data tracks changes to these objects and can reverse those changes on demand, such as when a user performs an undo command. Then, when it is time to save changes to your application's data, Core Data takes care of archiving the objects to a persistent store. And, it saves data into regular files that users can manage with the Finder, search with Spotlight, backup to CD, and email to friends, family, and coworkers.
