Some primary information about hibernate:

Main features

Hibernate is a solution for object relational mapping and a persistence management
solution or persistent layer.

What you can imagine is probably that you have your application with some functions
(business logic) and you want to save data in a database. When you use Java all the
business logic normally works with objects of different class types. Your database tables
are not at all objects.

Hibernate provides a solution to map database tables to a class. It copies the database
data to a class. In the other direction it supports to save objects to the database. In this
process the object is transformed to one or more tables.

Saving data to a storage is called persistence. And the copying of tables to objects and
vice versa is called object relational mapping.
