Abstract (Expand)

This paper presents formal approaches for assessing the integration of information system components. They were developed to support decisions in the strategic management of information systems. The fulfillment of integration requirements, the dependency of information system components on each other, and the heterogeneity of the integration infrastructure are the major assessment criteria.The meta-model 3LGM2A is the (semi-)formal base for methods introduced here. The fulfillment of integration requirements is checked by matching sets of application components that have specific requirements (requirements domains) with sets of application components that exchange data or call operations related to the requirements (communication domains). Requirements categories support the handling of the numerous specific requirements.For assessing the complexity of an information system or its subsystems the figures degree of informational dependence, degree of functional dependence, and degree of heterogeneity are defined.

Abstract (Expand)

Both regional health information systems and hospital information systems need systematic information management. Due to their complexity information management needs a thorough description or model of the managed HIS. The three layer graph based meta model (3LGM(2)) and the 3LGM(2) tool provide means for effectively modeling HIS. The 3LGM(2) tool has been used to build a model of the health information system of the German federal state Saxony. The model is not only used to support the further development of the Saxonian health information system but also for supporting strategic information management planning in the medical center of Leipzig University. Acceptance of the method depends strictly on its integration in management structures on the institutional, regional, national or even European level.
