History of Hibernate

Hibernate was developed in 2001 by Gavin king with his colleagues from Circus Technologies. The main aim was to provide better persistence capabilities than those of EJB2, by reducing the complexities and adding some missing features.

Hibernate is an ORM (Object-Relational Mapping) tool which simplifies the application development. Hibernate provides a framework that interacts with the data stored in the database, and it is a framework for Java EE 5. Gavin King has also contributed to the design of EJB 3.0 and JPA.

Following are the versions of Hibernate:

It runs on a platform known as JVM (Java Virtual Machine). Java Virtual Machine (JVM) is a virtual machine which is used to run Java programs and applications on the computer. Other language programs are also compiled to Java bytecode can be run on JVM. In other words, JVM is a virtual engine that serves the runtime environment to the Java programs and application. JVM converts Java bytecode into machine language.
