构件技术在医院信息管理系统重构中的应用研究

The Application Research Based on Component Technology is on the the Hospital Information Service System

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(HIS)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。最后通过其中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。

Component based software development （CBSD） has become the main means of software reuse. A reconiigurable strategy of a hospital information service system is presented which introduces three-tier B/S service model and uses CORBA criterion to build the business tier, via analyzing the function body of this system based on two-tier C/S architecture. At last, the reeonfiguration method is proved to be feasible by examples of designing PB NVO used in Patient Registration module of the Hospital Outpatient Service Chargeable subsystem.
