Both the way we look at data, through a DBMS, and the nature of data we ask a DBMS to manage have drastically evolved over the last decade, moving from text to images (and to sound to a lesser extent). Visual representations are used extensively within new user interfaces. Powerful visual approaches are being experimented for data manipulation, including the investigation of three dimensional display techniques. Similarly, sophisticated data visualization techniques are dramatically improving the understanding of the information extracted from a database. On the other hand, more and more applications use images as basic data or to enhance the quality and richness of data manipulation services. Image management has opened a wide area of new research topics in image understanding and analysis. The IFIP 2.6 Working Group on Databases strongly believes that a significant mutual enrichment is possible by confronting ideas, concepts and techniques supporting the work of researcher and practitioners in the two areas of visual interfaces to DBMS and DBMS management of visual data. For this reason, IFIP 2.6 has launched a series of conferences on Visual Database Systems. The first one has been held in Tokyo, 1989. VDB-2 was held in Budapest, 1991. This conference is the third in the series. As the preceding editions, the conference addresses researchers and practitioners active or interested in user interfaces, human-computer communication, knowledge representation and management, image processing and understanding, multimedia database techniques and computer vision.

This volume contains all papers presented at the Eighth European Meeting on Cybernetics and Systems Research. 169 draft papers were submitted for evaluation. In the process of careful refereeing, 33 papers were rejected and the remaining authors were invited to submit final papers. Out of these, 119 were accepted for presentation at the conference and publication in this volume. These papers were prepared by 173 scientists, authors and co-authors, from 22 European and non-European countries, with different cultural, social, and economic structures. Everybody tried hard to make this conference and its proceedings a true representation of state-of-the-art research worldwide: The members of the Programme Committee and the Chairmen of the Symposia were selected among the ~internationally leading scientists. Great care was taken not to make this conference a "European" or even "Austrian" one. We are happy and proud to hear that these "European Meetings" (the name is a purely traditional one) are recognized as the internationally leading conferences in cybernetics and systems research. Important scientists from allover the world carefully prepare their papers, containing their most recent research findings, and then enjoy the discussions with their co 11 eagues.

Logistics and fulfillment management is unglamorous, complex and expensive, but it is one of the primary factors determining whether an e-business will be profitable. Many enterprises (large and small) rush into the e-business model without adequate consi
