Introduction to Object-Relational Mapping with Hibernate

Brian Sam-Bodden, Integrallis Software, LLC

Track: Java
Date: Thursday, August 4th, 2005
Time: 5:20pm - 6:05pm
Location: E143-144

If you are an Enterprise Java developer, odds are that you’ll find yourself retrieving data to and from a relational database and you’ll want to look at ways to move that data to and from your objects and components. There’s also a very high probability that you’ll be working with an existing database schema that might predate any sort of object-oriented system.

Hibernate is an open source Object-Relational Mapping Framework that mostly automates the tedious and time-consuming task of persisting Java objects to a relational database. Hibernate is quickly becoming the preferred way for enterprise developers to overcome the object-relational impedance mismatch and a good alternative to the coarse-grained Entity EJBs, low-level raw JDBC, and by-committee specifications like JDO. Learn what your choices in the ORM arena, what to look for in an ORM tool, and how to get started with Hibernate for your next J2SE or J2EE project.

In this session you will learn:
- Understanding the O/R Impedance Mismatch
- Techniques of O/R Mapping
- Persistence Frameworks in Java
- Architecting Persistence into your application
- Hibernate Architecture and Overview
- Installing and configuring Hibernate in J2SE
- Hibernate in a J2SE application
- Mapping Persistence Classes
- Domain Models
- Object Identity
- Dealing with Inheritance and Schema Associations
- Understanding the lifecycle of persistent objects
- Understanding Hibernate usage in a J2EE application
- Overview of advanced topics
