The 3LGM2-tool to support information management in health care / Der 3LGM2-Baukasten zur Unterstützung des Informationsmanagements im Gesundheitswesen

Hospital information systems (HIS) as well as transinstitutional health information systems (tHIS) are constructed like a (complex of) building(s) out of different and probably heterogeneous bricks and components. Like an architect the information manager needs a description or model for the information system’s architecture respectively the enterprise architecture. 3LGM2 as a meta model has been designed to describe information systems (IS) by concepts on three layers. The meta model has been supplemented by the 3LGM2 tool. It enables information managers to graphically design even complex IS and provides means for analyzing information system’s quality and thus supports strategic, tactical and operational information management.
