In this tutorial, you will see how to persist the Java objects using the Hibernate Object/Relational Mapping (ORM) framework. Hibernate automates ORM and considerably reduces the number of lines of code needed to persist the object in the database. This example demonstrates how to automatically generate code from the object/relational mapping file, thus saving the developers time. This helps the developers focus on the business problem rather than doing repetitive coding work.
Hibernate uses an XML document or the properties file to define the object/relational mapping. The object/relational mapping file contains the mapping between the Java object and the corresponding database table. This example illustrates how to create the ORM using the XML document.
