Abstract:
In this paper, an XML-based approach is presented for the impact analysis of interface control in sustained systems. Once a system is completed developed, it goes into a sustained phase supported by many interfaces. As new technologies develop, updating and maintaining such systems require non-trivial efforts. A clear pre-requisite before the deployment of a new system is to clarify the influence of changes on other systems connected through interfaces. However, as each sustained system manages its own information separately, integrating relevant information among the interfaced systems is a major hurdle. In our approach, the XML technology is applied to support impact analysis for interface control architecture using change-detection approach for the reference. In particular, I focus on messaging interface issues in Health Level Seven typically used in medical information system and propose a scheme to represent message information that can be used for the decision support of interf
ace impact between sustained systems.
