Component-based development for supporting workflows in hospitals.
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.
