*** Course delivered in English (UK) *** JPA and Hibernate Course Overview

Hibernate is the primary JPA implementation and the most popular Java ORM framework. It dramatically reduces boilerplate code,eliminates vendor specific SQL,and eases the reading and writing of composite objects and specialisations to the database.

This JPA and Hibernate course delivered using JPA v3 and Hibernate v6,focuses on the practical aspects of using the framework as part of the technology stack. Attendees will learn how to persist the instances of classes that follow natural object-oriented idioms including composition and inheritance.

Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.
