Hibernate是一个开放源代码的对象关系映射框架，它对JDBC进行了非常轻量级的对象封装，使得Java程序员可以随心所欲的使用对象编程思维来操纵数据库。 Hibernate可以应用在任何使用JDBC的场合，既可以在Java的客户端程序实用，也可以在Servlet/JSP的Web应用中使用，最具革命意义的是，Hibernate可以在应用EJB的J2EE架构中取代CMP，完成数据持久化的重任。-Hibernate is an open source object-relational mapping fr a mework, it had a very lightweight JDBC object package so that Java programmers can use arbitrary objects to manipulate database programming thinking. Hibernate can be applied to any use of JDBC occasion, either in the Java-client program useful, can also Servlet/JSP in Web applications, the most revolutionary is that, Hibernate to EJB in the application of the J2EE architecture to replace the CMP to complete the important task of data persistence.
