An Introduction to Operators on the Hardy-Hilbert Space

This book describes modern methods for developing enterprise-wide information systems. The proven "Architecture of Integrated Informations Systems (ARIS)" is used as framework for the development of business process models for industrial companies. For the processes of logistics, product development, information and coordination the ARIS-architecture serves as basis for a description from the functional, organizational, data and process viewpoint. The developed reference models can be used right away to support the introduction of new organizational concepts through the employment of new information processing techniques. A wealth of graphical illustrations enhance the reader's understanding of the material. Examples from standard software systems (SAP/R3) demonstrate the book's down-to-earth practicality.
