前書き

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.

Hibernateやオブジェクト/リレーショナルマッピング、 さらにはJavaが初めての方は、以下のステップに従ってください：

  1. 章 1. Tutorial を読んでください。 段階的に解説していきます。 チュートリアルのソースコードはディストリビューションの doc/reference/tutorial ディレクトリに含まれています。

  2. 章 2. アーキテクチャ を読んで、Hibernateが利用可能な環境を理解してください。

  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. FAQはHibernateウェブサイトにあります。

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

  7. Hibernateウェブサイトのコミュニティエリアは、デザインパターンやさまざまな統合ソリューション （Tomcat, JBoss AS, Struts, EJB, 等）についてのよい情報源です。

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.
