What is Hibernate ?

Hibernate is a tool that is used for object-related mapping in the Java programming language. It handles the problems that arise out of the object-relational impedance mismatch and replaces direct and persistent database accesses with the help of high-level object handling functions.

The main purpose of this tool is to map the Java classes to database tables and mapping the Java databases to the SQL data types. Hibernate also provides the facilities of data retrieval and queries.

It can generate the SQL calls and relieves the developers from the manual control and object conversation of the outcome set.
