Introduction
"Java
and databases make a powerful combination. Getting the two sides to work
together, however, takes some effort. For many Java developers, it's the least
pleasant part of their work. Even database experts, who may enjoy fiddling with
SQL, dread the tedious plumbing and typographical spaghetti needed to put their
SQL into a Java program. It comes down to the plain fact that Java deals in
objects while most databases do not. In the ongoing effort to automate the
task, the Hibernate persistence framework has emerged as a powerful contender:
programmers write natural Java objects and some simple configuration files, and
Hibernate automates all the interactions between the objects and the database.
This book covers Hibernate's primary
features, such as mapping from Java classes to database tables and from Java
data types to SQL data types, as well as Hibernate's data query and retrieval
facilities. Harnessing
Hibernate also shows how to:
á
Perform object/relational
mapping
á
Work with persistent data
from Java code
á
Work with groups and
relationships between objects
á
Extend Hibernate's rich
type support for your own needs
á
Simplify query creation
using criteria and examples
á
Use the Hibernate Query
Language (HQL) and understand how it differs from SQL
á
Use Hibernate in
conjunction with Spring
á
Use Hibernate in
conjunction with other packages, such as the Stripes web framework and the
Eclipse IDE
If you
find using SQL to be a chore, Harnessing Hibernate offers you an effective and painless method for working
with the information you store in your applications."
What I Learned
Do I use Java? Not intentionally. But if I did (and I
probably should know more, but I'm into this "Ruby" thing latelyÉ),
I'd want to know how to use this object/relational mapping service tool. This book builds on the Developer's
Notebook Series and has evolved from the earlier Notebooks into a full-blown
stand-alone book.
Conclusions
If you are into Libraries, Frameworks and Components and
need to store and is use information in relational database environments and
work in a JDBC (Java Database Connectivity) environment, make it
easy on yourself and get this book.
