三层C/S模型在药品管理中的应用

Application of three-tier C/S model in medical management

三层client/server结构是数据库应用开发的新趋势,文章对三层client/server的体系结构、主要特点进行了分析,提出了三层结构设计的框架,并结合实例——药品管理子系统,探讨了基于组件的逻辑上三层结构的数据库应用的实现过程,说明了三层结构具有较好的灵活性、易维护和可重用性。

Three-tier client/server structure reflects the newest developing tread of database application. The architect and the feathers of the three-tier client/server structure are introduced and the design framework of three-tier structure is presented. Finally, combining with an example, medical storage management subsystem, the process of realizing the database application is discussed based on the component. It shows that the three-tier structure has better maintenance and reusability and flexibility.
