Concept of ORM

Hibernate is an Object-Relational Mapping(ORM) framework which maps Java classes to database tables and do the persistent operations like save,update and delete.

Lets assume we need to save Student object in students table. In this way we need to either get each values from object then set to JDBC Statement. This is tedious task for java programmers. ORM framework removes this drawback and provides object persistent.
