【摘要】 基于构件技术的软件开发已经成为软件复用的主要手段。通过分析某两层C/S结构医院信息管理系统功能体,引入三层B/S体系结构,并应用CORBA规范建立系统业务逻辑层,以实现医院信息管理系统的重构。最后通过某医院门诊收费子系统的病人挂号模块的PB构件设计实例,说明该重构方法是可实现的。更多还原

【Abstract】 Component-based software development(CBSD) has become the main means of software reuse.A reconfigurable strategy of a hospital information service system is presented,three-tier B/S service model is introduced and CORBA criterion is used to build the business tier,by analyzing the function body of this system based on two-tier C/S architecture.Finally,the reconfiguration method is proved to be feasible by examples of designing PB NVO used in Patient Registration module of the Hospital Outpatient Service Chargeable subsystem.更多还原
