Object Relational Mapping with Hibernate
In this chapter you have learned the foundations of object-relational mapping using Hibernate, the prevalent and by far richest mapping service available. Now that you know how to map simple classes and collections and how to deal with inheritance, you’ll be ready to tackle the development of the TechConf application Data Access Objects (DAO) in subsequent chapters.
We will continue to learn about Hibernate features, including more advanced features such as caching and other facilities that will come into play when we transition into the world of J2EE by having our Hibernate-mapped POJOs working inside an EJB container. Also, in the Testing chapter, you’ll learn how to apply some of the techniques of unit and integration testing to the testing of Hibernate-mapped POJOs and Hibernate-powered DAOs.
