Introduced in Mac OS X "Tiger" 10.4, Core Data is Apple's new object persistence framework. If you're still manually reading and writing custom data structures to disk, you're simply working too hard.
Core Data follows the object-relational design pattern, and sports visual definition of data models using Apple's free IDE: Xcode 2. It supports a number of file formats: proprietary binary, textual XML and SQLite. Core Data is worth using even if you have a custom file format, as it manages your in-memory object graph for you, complete with niceties like automatic undo.
Together we'll build a Core Data application from scratch, illustrating defining a new data model, creating objects in memory, hooking them up to a user interface, writing them to disk, and reading them back. I'll also compare and contrast Core Data to Apple's other object-relational persistence framework: Enterprise Objects Framework (EOF).
