Working with both Object-Oriented software and Relational Databases can be cumbersome and time consuming.

Probably the single best background is an understanding of data modeling principles.

You might want to consider these resources as a good starting point: Hibernate not only takes care of the mapping from Java classes to database tables (and from Java data types to SQL data types), but also provides data query and retrieval facilities.

It can significantly reduce development time otherwise spent with manual data handling in SQL and JDBC.

Hibernate’s design goal is to relieve the developer from 95% of common data persistence-related programming tasks by eliminating the need for manual, hand-crafted data processing using SQL and JDBC.

The tutorial is based on an earlier tutorial developed by Michael Gloegl.

All code is contained in the This tutorial expects the user have knowledge of both Java and SQL.

If you have a limited knowledge of JAVA or SQL, it is advised that you start with a good introduction to that technology prior to attempting to learn Hibernate.

However, unlike many other persistence solutions, Hibernate does not hide the power of SQL from you and guarantees that your investment in relational technology and knowledge is as valid as always.

Hibernate may not be the best solution for data-centric applications that only use stored-procedures to implement the business logic in the database, it is most useful with object-oriented domain models and business logic in the Java-based middle-tier.

However, Hibernate can certainly help you to remove or encapsulate vendor-specific SQL code and will help with the common task of result set translation from a tabular representation to a graph of objects.

If you are new to Hibernate and Object/Relational Mapping or even Java, please follow these steps: Intended for new users, this chapter provides an step-by-step introduction to Hibernate, starting with a simple application using an in-memory database.
