Java EE Programming: Hibernate, Part 1 of 3

Course description

As data models get more complex it becomes harder for programmers to create applications to access that data. Enter Java Hibernate. Hibernate is a middle-tier developer framework for Object to Relational Mapping (ORM). A Hibernate tier is used as a go-between from the data tier to the client tier thus creating an automatic translation between the Object Oriented model and the required relational data model. This course will start you on the journey to understand Hibernate. First, you will cover the basics of what Hibernate is and what it does. Next, move to ORM and persistence in class mappings and many other items. Then you will see Value types, components and Collections and finish up with Entity Associations.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.

Prerequisites

This course assumes you are familiar with object-oriented principals and have a solid practical understanding of polymorphism in Java. You must also have a working knowledge of Eclipse IDE for Java EE.
