Abstract
Object-oriented (OO) applications almost always involve a domain model representing the business entities that the application deals with. Our gTunes application will include a number of domain classes including Artist, Album, and Song. Each of these domain classes has properties associated with it, and you must map those properties to a database in order to persist instances of those classes.
