Building Robust Integration Tiers with Hibernate

This Extreme Learning expert-led course will teach you how to use Hibernate as a persistence framework for building the ORM layer of a Java technology-based object-oriented application. It covers the deep dive principles of object-relational mappings and their implementation in Hibernate, one of the more popular ORM frameworks in the marketplace. Once they complete the course, students will be able to build Java technology applications that require the management of persistent information, leveraging Hibernate to provide the bridge between the object-oriented representation used at application-level and the relational representation required by many target relational databases. Oracle and MySQL use cases are covered.

About Extreme Learning: Get taught directly by the experts and interact with peers in an engaging informal environment. These are intensive, deep dive training sessions designed for advanced IT professionals which incorporate expert-led presentations and hands-on labs.
