Core Data is a great API for managing data, in conjunction with Cocoa Bindings, within an application. Core Data is great for building well-factored applications based on the Model-View-Controller (MVC) pattern by providing a strong, flexible, and powerful data model framework. You can read more about it on Apple's Core Data Page
Marcus Zarra recently did a good job introducing Core Data on Late Night Cocoa which is certainly worth a listen if you're new to Core Data, or even an "old hat" with the framework.
