| 摘 要： | 基于SQL的JDBC持久化技术和基于对象/关系映射（ORM）的面向对象持久化技术都会导致系统紧耦合。针对上述问题,通过研究Java持久化API（JPA）ORM技术、JPA模型和JPA接口,提出并实现一种灵活的数据持久化模型。该模型与ORM框架松耦合,可以简化对象持久化的开发,加快应用系统的开发速度。

| Abstract: | Persistence technology of Java Database Connectivity(JDBC) based on SQL and object-oriented persistent technology based on Object/Relation Mapping(ORM) make the system in high coupling. Aiming at such problem, this paper researches Java Persistence API(JPA) ORM technology, JPA model and JPA interfaces, designs and implements a flexible data persistence model, which uncouples with ORM framework and reduces the coupling of the system, so that it is easy to develop object persistence and accelerates the developing speed of application systems. |
