In this four-day course you will be introduced to Hibernate and learn how to do Object Relational Mapping using Hibernate. You will learn about value types, collections and components, entity associations (relations) and the mapping of inheritance. Next the use of persistent objects is covered and reading, updating and deleting objects as well transactions is discussed. Finally, if time permits, attention is payed to querying in Hibernate.
