Summary

This book provides current, up-to-date information about Hibernate 3 that programmers can't get anywhere else. Not only is it the first book to cover Hibernate 3 and all of the new features, it also provides an introduction to the latest version of this apparent established standard for object relational persistence in the Java world. Linwood and Minter discuss the new Hibernate 3 persistence layer and share design tips and best practices-not just the "how to" use parts of Hibernate, but how to take a step back and solve problems. They also approach Hibernate as software developers who use it and share knowledge, rather than as documenters of a project they worked on. This book is appropriate for programmers experienced in using Java with databases but inexperienced in Hibernate. It also can be useful to programmers who have some familiarity with Hibernate 2 and want to learn the nuances of version 3.
