Basic Architecture of Hibernate

Introduction to Hibernate:

Hibernate is an Object-Relational Mapping (ORM) solution for JAVA. It is a powerful, highperformance object/relational persistence and query service. It allows us to develop persistent classesfollowing object-oriented idiom – including association, inheritance and polymorphism.

Hibernate Architecture

1) itself opens connection to database,

2) converts HQL (Hibernate Query Language) statements to database specific statement,

3) receives result set,

4) then performs mapping of these database specific data to Java objects which are directly used by Java application.

Hibernate uses the database specification from Hibernate Properties file. Automatic mapping is performed on the basis of the properties defined in hbm XML file defined for particular Java object.
