![]() ![]() It provides a framework for mapping an object-oriented domain model to a relational database. It wraps JDBC and works as a factory for . Hibernate ORM (or simply Hibernate) is an objectrelational mapping tool for the Java programming language. It is an open source persistent framework started by Gavin King in 2001. Session (): Session is a single-threaded, short-lived object representing a conversation between the application and the persistent store. Hibernate framework is an object-relational mapping library for the Java language. Although mapping of basic Java classes is in-built in Hibernate, mapping of custom types is often complex. When you design a class to be persisted by Hibernate, it is important to provide JavaBeans compliant code as well as one attribute, which would work as index like id attribute in the Employee class. We can get instance of using SessionFactory. Even SQL abstraction layers, like the Hibernate Query Language (HQL) have the. Let us consider our Employee class with getXXX and setXXX methods to make it JavaBeans compliant class.Ī POJO (Plain Old Java Object) is a Java object that doesn't extend or implement some specialized classes and interfaces respectively required by the EJB framework.

Java Hibernate allows you to create, save, and update data objects in a supported database. Now that we have looked at a small preview of Hibernate-related Java code and XML files, let's get a high-level understanding of some basic Hibernate. ![]()
