摘　　要：目前国内在开发企业级系统时,对表示层和业务层的研究比较多,但对如何利用正规的持久性框架建立数据层却研究很少。从体系结构的角度,利用设计模式思想构建持久性框架,使系统能够做到随需应变,当企业应用发生变动时,只要对该框架进行少量修改,即可满足新的应用,而不用重建整个系统。At present, research about presentation tier and business tier is emphasized during the development of the enterprise-oriented system. However, it is neglected to study the construction of data access tier based on persistence framework. From the view of architecture to construct persistence framework is discussed by using design pattern, this framework can make the system agile and alterable, when enterprise application changes, the only need is to modify a little part of it, the whole system does not.need to be rebuilt.
