Hibernate: A Developer's Notebook
Samenvatting
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.
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.
