    Integration von Daten, Anwendungen und Prozessen am Beispiel des Telekommunikationsunternehmens EWE TEL
    (Wirtschaftsinformatik: Vol. 44, No. 5, 2002) Bunjes, Bernd; Friebe, Jörg; Götze, Rainer; Harren, Arne
    The necessary specialisation in information processing in the telecommunication sector led to a wide range of software systems in the relevant software market. This can be traced back by the fact that there is a lack of capable and integrated solutions. If a telecommunication company comes to the decision to use specialised software systems, it has to face the sophisticated challenge of systems integration. This can be done at least at the levels of data, applications and processes. Illustrated by examples from the heterogeneous system environment at the telecommunication company EWE TEL, concepts for system integration and gained experiences are presented in this article. The following aspects are discussed in detail: integration of data by means of middleware, integration of applications using application server technology, and integration of processes by employing workflow management systems.

    Kopplungsstrategien für Anwendungssysteme im Krankenhaus
    (Wirtschaftsinformatik: Vol. 44, No. 5, 2002) Niemann, Heiko; Hasselbring, Wilhelm; Wendt, Thomas; Winter, Alfred; Meierhofer, Matthias
    The realization of specific coupling strategies and integration techniques is discussed exem-plarily for a university hospital, the Universitätsklinikum Leipzig (UKL) in Germany. The integration of the central patient management system serving the administrative department with the clinical workplace systems serving hospital wards is presented. We analyse the integration with respect to the underlying theoretical conceptions and discuss information management issues for deployment and maintenance of the overall IT infrastructure. This paper presents the pros and cons of synchronous and asynchronous patient data replication, the practical experience with the deployment of a communication server, and the experience with using an RFC interface, a proprietary interface to the enterprise resource planning system SAP R/3. Both, organizational and technical issues are addressed in this context.
