Today this gap has almost completely disappeared, and we can now first and fore-most rely on the standardized API and architecture of Java Persistence. The last edition was therefore a large book, because many examples had to be shown in the old form and the new, standardized form. When we wrote the previous edition of this book, Hibernate was undergoing some significant changes: grown organically and driven by an open source community and the daily requirements of Java developers, Hibernate had to become more formal and implement the first version of the JPA specification. Other related projects such as Hibernate Search, Hibernate Bean Validation, and more recently Hibernate object/grid mapping (OGM) are delivering new and innova-tive solutions that make Hibernate a complete tool kit for a diverse range of data-management tasks. The core of Hibernate, or what is now called object/relational mapping (ORM), has been mature for a long time, and many small improvements have been made over the years. The fifth major Hibernate release is now available, as well as the second major ver-sion of the Java Persistence API specification (JPA) implemented by Hibernate. It’s also a testament to the quality of specifications and tools available, which today make it easy to start a project and to estimate and reduce risk when build-ing large, complex applications.

This shows that SQL databases are still the preferred technology for reliable data storage and management, especially in the Java enterprise software devel-opment space. In a recent poll, Hibernate was among the top five tools used by many Java devel-opers every day. This is our third book about Hibernate, an open source project that is almost 15 years old.
