/**
 * JPetStore primary business object.
 * 
 * <p>This object makes use of five DAO objects, decoupling it
 * from the details of working with persistence APIs. So
 * although this application uses iBATIS for data access,
 * a different persistence tool could be dropped in without
 * breaking this class.
 *
 * <p>The DAOs are made available to the instance of this object
 * using Dependency Injection. (The DAOs are in turn configured using
 * Dependency Injection themselves.) We use Setter Injection here,
 * exposing JavaBean setter methods for each DAO. This means there is
 * a JavaBean property for each DAO. In the present case, the properties
 * are write-only: there are no corresponding getter methods. Getter
 * methods for configuration properties are optional: Implement them
 * only if you want to expose those properties to other business objects.
 *
 * <p>There is one instance of this class in the JPetStore application.
 * In Spring terminology, it is a "singleton", referring to a
 * per-Application Context singleton. The factory creates a single
 * instance; there is no need for a private constructor, static
 * factory method etc as in the traditional implementation of
 * the Singleton Design Pattern. 
 *
 * <p>This is a POJO. It does not depend on any Spring APIs.
 * It's usable outside a Spring container, and can be instantiated
 * using new in a JUnit test. However, we can still apply declarative
 * transaction management to it using Spring AOP.
 *
 * <p>This class defines a default transaction annotation for all methods.
 * Note that this annotation definition is only necessary for auto-proxying
 * driven by JDK 1.5+ annotations (see the "annotation" directory under the root
 * of JPetStore). No annotations are required with a TransactionFactoryProxyBean,
 * as in the default applicationContext.xml in the war/WEB-INF directory.
 *
 * <p>The following annotation is Spring's JDK 1.5+ Transactional annotation.
 *
 * @author Juergen Hoeller
 * @since 30.11.2003
