Other applications — for example, iTunes — might assist users in organizing, sorting, and managing media files like music and video.
So many applications helping users with data aren't a surprise. Computers are exceedingly good at managing data, and lots of it. What might be surprising though is that programmers usually have to do all the hard work of writing code to handle all this data — until now. In this chapter, I show you how Cocoa makes adding data management to your projects easy with Core Data.

Core Data is a relative newcomer to the Cocoa programming scene, but don't let its youth and inexperience dissuade you from unleashing its talents. Core Data is a framework of around a dozen pre-made classes that allows you to easily add data management to your applications.
