JA08 - Hibernate Development - 3 Days


Course Description

Hibernate is a popular object-relational mapping framework for Java applications. Using Hibernate, you can implement enterprise applications based on objects, relying on Hibernate to map the objects to persistent storage in the database.

This course describes Hibernate ORM techniques, showing how to map complex data relations to object hierarchies and how to manage the lifetime and persistence of these objects.
