摘　　要：以往在基于J2EE应用系统开发中,复杂的业务逻辑和数据逻辑混杂,使得系统处于紧耦合状态。文章通过对传统持久化方法的深入分析,引出了基于ORM的数据持久性概念,并说明其优越性。依据这一概念,进一步引出基于ORM的数据持久层框架—Hibernate。In the development of J2EE based application systems,complex business logic and data logic are mixed,making the system in a tight coupling state.Through an in-depth analysis of the traditional method of persistence,this paper introduces the concept of data persistence based on ORM and illustrates its advantages.Based on this concept,Hibernate,a data persistence layer framework based on ORM,is further derived.

关 键 词：J2EE 对象关系映射 数据持久层 HIBERNATE
