Hibernate is popular open source ORM (Object Relation Mapping) tool for Java platform, for mapping an entity to a traditional relational database like Oracle, MySQL etc

By using Hibernate, we can done database operations like Create, Read, Update & Delete etc, with very little code.

We can also use Hibernate Query Language (HQL) for the jdbc operation, you can see an example of Hibernate Query Tutorial
