Title: All Together Now - Towards Integrating the World's Information Systems
Abstract. Over the past decades, most enterprises and administrations have introduced computerized information systems for many purposes, often even several of them in the same institution. Today's desire for ever more comprehensive automization usually requires that various individual systems are brought together "under one single roof". Furthermore, enterprise takeovers and mergers as well as the foundation of virtual enterprises bring along quite similar tasks. From a computer science point of view, the problem of integrating different information systems that have grown individually proves to be a rather sophisticated one, and unfortunately a simple uniform solution is not in sight. This talk will first present an array of details involved in the problem that will influence potential solutions. Subsequently, a simple reference architecture will be used to show the principal solutions that are conceivable. For the most promising ones, we will then dwell a bit deeper into their characteristics and challenges. We conclude by sketching some ongoing own research in this area.
Klaus R. Dittrich holds the chair for information systems at the Department of Information Technology at the University of Zurich, Switzerland, and heads the Database Technology Research Group at this place (see here for more information). Since many years, he has taught and conducted research in various areas of database systems and their applications, partly in cooperation with industry and within international settings like ESPRIT, and he has also consulted with many industries and government. In particular, he has followed the development of object-oriented technologies from their inception, and has influenced the area of object databases with own contributions. He coorganized the first-ever ooDBMS-Workshops in 1986 and 1988, and has been a co-author of the "Object-oriented Database Manifesto" in 1989. Other areas of research interest include active database systems, federated database systems, database architecture, and the "intersection" of database technology and software engineering. He has published widely, and has lectured and conducted professional seminars in some 25 countries all over the world. As a visiting scientist, he has been invited to IBM Almaden Research Center, Hewlett-Packard Laboratories, Stanford University and the University of Aalborg/Denmark. He is currently the secretary of the VLDB Endowment, and has been elected as a member of the IEEE Distinguished Visitor Program Europe for the next three years.
