Hibernate Training (3 days)

Java Persistence with Hibernate Course Overview

This course develops skills in using the Object/Relational Mapping tool Hibernate®. The course uses the latest release version of Hibernate, 3.2, which is directly related to the new EJB 3.0 version defined in Java EE 5.0.

By the end of the course, students will be prepared to set-up and use Hibernate as the persistence mechanism in Java applications.

A bridge module is also available that illustrates how the Spring framework's persistence module compliments Hibernate; this brief presentation can easily be added to the end of the class and works especially well to cap off a week of training using this course and one of our Spring courses.

Java Persistence with Hibernate Course Goals

• Configure Hibernate using both properties files and XML documents.
• Create mapping documents for Java classes.
• Define object relationships and build mapping documents to model them.
• Use components to model composition relationships in the object model.
• Work with one-to-one, many-to-one, and many-to-many relationships.
• Evaluate the different approaches to modeling inheritance and polymorphism in database schema.
• Build Java applications that use Hibernate to create, retrieve, update, and delete objects.
• Use Hibernate's Criteria Query API to do searches and Query By Example.
• Work with Hibernate Query Language (HQL) to generate object-based SQL.
• Understand Hibernate sessions and transactions and their impact on performance.

Java Persistence with Hibernate Course Prerequisites

Experience in the following areas is required:

• Intermediate knowledge of Java programming;
• Some familiarity with SQL, relational databases, and the Java Database Connectivity (JDBC) interfaces will be helpful;
