Java Persistence API (JPA) is a Java specification that provides certain functionality and standard to ORM tools. The ORM tool internally uses the JDBC API to interact with the database. It is a programming technique that maps the object to the data stored in the database. Hibernate implements the specifications of JPA (Java Persistence API) for data persistence.Īn ORM tool simplifies the data creation, data manipulation and data access. It is an open source, lightweight, ORM (Object Relational Mapping) tool. Hibernate is a Java framework that simplifies the development of Java application to interact with the database. It was started in 2001 by Gavin King as an alternative to EJB2 style entity bean.
