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’ll cover the basics of what Hibernate is and what is does. Then move to ORM and persistence in class mappings and many other items. Then you’ll see Value types, components and Collections and finish up with Entity Associations.
