Working with object-oriented software and a relational database can be cumbersome and time consuming in today's enterprise environments. Hibernate is an Object/Relational Mapping tool for Java environments. The term Object/Relational Mapping (ORM) refers to the technique of mapping a data representation from an object model to a relational data model with a SQL-based schema.

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

Hibernate's goal is to relieve the developer from 95 percent of common data persistence related programming tasks. 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.

Si vous êtes nouveau dans Hibernate et le mapping Objet/Relationnel voire même en Java, suivez ces quelques étapes :

  1. Lisez Chapitre 1, Tutorial pour un didacticiel plus long avec plus d'instructions étape par étape.

  2. Lisez Chapitre 2, Architecture pour comprendre les environnements dans lesquels Hibernate peut être utilisé.

  3. View the eg/ directory in the Hibernate distribution. It contains a simple standalone application. Copy your JDBC driver to the lib/ directory and edit etc/hibernate.properties, specifying correct values for your database. From a command prompt in the distribution directory, type ant eg (using Ant), or under Windows, type build eg.

  4. Use this reference documentation as your primary source of information. Consider reading [JPwH] if you need more help with application design, or if you prefer a step-by-step tutorial. Also visit http://caveatemptor.hibernate.org and download the example application from [JPwH].

  5. Les questions les plus fréquemment posées (FAQs) trouvent leur réponse sur le site web Hibernate.

  6. Links to third party demos, examples, and tutorials are maintained on the Hibernate website.

  7. La zone communautaire (Community Area) du site web Hibernate est une bonne source d'information sur les design patterns et sur différentes solutions d'intégration d'Hibernate (Tomcat, JBoss, Spring Framework, Struts, EJB, etc).

If you have questions, use the user forum linked on the Hibernate website. We also provide a JIRA issue tracking system for bug reports and feature requests. If you are interested in the development of Hibernate, join the developer mailing list. If you are interested in translating this documentation into your language, contact us on the developer mailing list.

Le développement commercial, le support de production et les formations à Hibernate sont proposés par JBoss Inc (voir http://www.hibernate.org/SupportTraining/). Hibernate est un projet Open Source professionnel et un composant critique de la suite de produits JBoss Enterprise Middleware System (JEMS).
