DAOs and Querying

In this chapter, we introduced some core ORM concepts, and you learned more about how Spring and Hibernate can be used together. We also reviewed some key design patterns that are instrumental to the way in which Spring integrates with many persistence frameworks. Through our gallery application examples, we demonstrated how to implement an effective DAO layer. We examined several options for integrating Hibernate—using the HibernateTemplate as well as using the Hibernate Core APIs.
