Do you enjoy writing software, except for the database code? Hibernate:A
Developer's Notebook is for you. Database experts may enjoy fiddling
with SQL, but you don't have to--the rest of the application is the fun part.
And even database experts dread the tedious plumbing and typographical spaghetti
needed to put their SQL into a Java program. Hibernate: A Developers
Notebook shows you how to use Hibernate to automate persistence: you write
natural Java objects and some simple configuration files, and Hibernate
automates all the interaction between your objects and the database. You don't
even need to know the database is there, and you can change from one database to
another simply by changing a few statements in a configuration file.
Hibernate: A Developer's Notebook walks you through the ins and
outs of using Hibernate, from installation and configuration, to complex
associations and composite types. Two chapters explore ways to write
sophisticated queries, which you can express either through a pure Java API, or
with an SQL-inspired, but object-oriented, query language. Don't let that
intimidate you though: one of the biggest surprises in working with Hibernate is
that for many of the common real-world application scenarios, you don't need an
explicit query at all. If you've needed to add a database backend to
your application, don't put it off. It's much more fun than it used to be, and
Hibernate: A Developer's Notebook shows you why. Here's what a
few reviewers had to say: "I'm sitting on an airplane after finishing
Hibernate: A Developer's Notebook. It's rare to find a book on a new Java
technology that you can get through on a domestic flight. That this notebook
effectively and succinctly tackles object-relational mapping makes it, and
Hibernate, even more impressive. Many books in this category would need to be
checked luggage. With this book, you travel first class." --Mike Clark
"A simple persistence framework deserves a simple book, and this one
delivers. The examples are well described and easy to understand, yet
sophisticated enough to demonstrate Hibernate in a real-world context. Jim, I'm
a new fan." --Bruce Tate About the new Developer's Notebook Series
from O'Reilly: Developer's Notebooks are a new book series covering
important new tools for software developers. Developer's Notebooks stress
example over explanation and practice over theory. They are about learning by
doing; by experimenting with tools and discovering what works. "All lab,no
lecture," with a thoughtful lab partner to guide the way
