Part III: Conversational object processing

In this part of the book, we explain how to work with persistent objects. Chapter 9 shows you how to load and store objects with the Hibernate and Java Persistence programming interfaces. Transactions and concurrency control are another important topic, discussed in detail in chapter 10. We then implement conversations in chapter 11 and show you how this concept can improve the design of your system. chapters 12 and 13 focus on efficiency and how Hibernate features can make your life easier when you have to load and modify large and complex datasets. Querying, query languages, and APIs are examined in detail in chapters 14 and 15. In chapter 16, we bring it all together by designing and testing a layered application with ORM persistence.

After reading this part, you'll know how to work with Hibernate and Java Persistence programming interfaces and how to load, modify, and store objects efficiently. You'll understand how transactions work and why conversational processing can open up new ways for application design. You'll be ready to optimize any object modification scenario, write complex queries, and apply the best fetching and caching strategy to increase performance and scalability.
