Leopard Sample Code: Cocoa
Data management in Cocoa involves the creation and handling of the various types of data available to a program, such as strings, collections, binary data, dates, property lists, and XML data. Using the Cocoa programming interfaces for these types, developers can, for example, calculate the interval between two dates or record operations so that users can reverse an operation's effect.
