Changing requirements for health care information systems force the development of an open, modular architecture in which components can be integrated. This offers a flexible means for integrating different (heterogeneous) systems used by different users. Selecting the components to integrate, and determining the 'right way' to integrate them, necessitates a shift in focus towards the business process to be supported. The realization of such an open, modular architecture is a difficult task. It consists of breaking down existing systems in required components and integrating these and other components. Many authors on component-based development strategies focus attention on the technological issues of component integration (do we use CORBA, DCOM/OLE, or EDI?). This paper presents an approach for determining the required components, and the way they have to be integrated, based on an analysis of the business process to be supported, and the information systems currently used.
医疗保健信息系统不断变化的需求促使开发一种开放的模块化架构，在这种架构中组件能够实现集成。这为整合不同用户使用的不同（异构）系统提供了一种灵活的方式。选择要集成的组件并确定集成它们的“正确方法”，需要将重点转向所支持的业务流程。实现这样一种开放的模块化架构是一项艰巨的任务。它包括将现有系统分解为所需的组件，并将这些组件与其他组件进行集成。许多关于基于组件的开发策略的作者都将注意力集中在组件集成的技术问题上（我们是使用CORBA、DCOM/OLE还是EDI？）。本文提出了一种基于对所支持的业务流程以及当前使用的信息系统的分析来确定所需组件及其集成方式的方法。
