What You'll learn

Explain how the issues associated with object persistence in a relational model are addressed by Hibernate
Understand the relationships between SQL, Java, JDBC, Spring, Java Persistence API, EJB 3.0, and Hibernate
Write applications that take advantage of the Hibernate Persistence Manager.
Map Java classes to relational tables.
Capture both relational and inheritance associations in metadata using either XML or the Java Annotation mechanism.
Create and use mappings between Java classes and relational databases.
Understand how identity and keys are handled in Hibernate.
Understand the persistent object lifecycle and how that relates to transactions and concurrency.
Become familiar with the mapping of entity associations to database tables
Query for data using the Java Persistence Query Language (JPQL) and the Criteria API
