EDBT 2000 is the seventh conference in a series dedicated to the advancement of database technology. This year’s conference special theme, \Connect Millions of Users and Data Sources," underscores the importance of databases for the information age that is dawning with the new millennium. The importance - rives not just from the observation that the information age essentially rests on theconvergenceofcommunications,computing,andstorage.Equallyimportant, many of the concepts and techniques underlying the success of databasesystems have independent meaning and impact for today’s distributed information s- tems. The papers in the volume should also be seen in this light. The EDBT 2000 conference program includes 30 research papers selected by the program committee out of 187 submissions, covering advances in research, development, and applications of databases. The conference program also - cludes six industry andapplications papers,a panel discussion,six tutorials,and several software demonstrations. The conference features three distinguished - vited speakers: Ashish Gupta discusses database issues in electronic commerce, Stefano Ceri addresses the impact and challenges of XML on databases, and Andreas Reuter shares his views on new perspectives on database technology. The technical contributions presented at the EDBT 2000 conference are colle- ed and preserved in this volume that we are pleased to present to you with the expectation that it will serve as a valuable research and reference tool in your professional life.

This book discusses the maturity of today's database technology in the light of the needs of engineering applications and industrial automation. Those at the forefront of database research come up with new techniques to satisfy new needs, but today's engineering community must live with database systems that reflect the older state of the art. The purpose of the book is to demonstrate that even though solutions based on today's technology are less than perfect, they do provide solutions to current pressing problems. The book mainly covers current database technology and its applications, but also mentions some promising techniques under research in order to prepare the reader for the future. The book contains four chapters that cover the significance of engineering databases, the current state of database technology, the utilization of engineering databases, and two extensive case studies. For cursory reading, the chapters may be considered to be self-contained. Intended readers are middle management and engineers from industry who deal with automation both as users and vendors, consultants to such industry, vendors of database systems, and lecturers and students.The book requires no special background in informatics.

Die Unternehmensführung ist heute auf umfassende, aber korrekte, vor allem strukturierte, vom Außendienstmitarbeiter unbeeinflußte Informationen über den Wirkungsgrad des Außendienstes und über das Marktgeschehen angewiesen. Das Forschungszentrum Informatik an der Universität Karlsruhe und die Fraunhofer-Arbeitsgruppe Graphische Datenverarbeitung, Darmstadt, bearbeiten deshalb ein gemeinsames Projekt AUDIUS zur Unterstützung des Außendienstes durch DV-Systeme. Das Buch enthält eine ausführliche Analyse der Aufgaben des Außendienstes, seiner Ziele und Probleme sowie der an ihn gestellten Anforderungen. Es gibt einen Überblick über den Stand der Technik bei den Komponenten, die im Rahmen eines integrativen DV-Ansatzes zur Unterstützung des Außendienstes Verwendung finden können. Ein erstes Grobkonzept einer modularen, flexibel konfigurierbaren Basisarchitektur und Strategien zur Einführung eines solchen Systems werden vorgestellt. Das Buch wendet sich an Fachleute aus der Praxis, die Anbieter oder Anwender derartiger Systeme werden wollen, sowie an Wirtschaftswissenschaftler und Ingenieure mit Interesse an Arbeitsorganisation.

Datenbanken spielen als Informationsspeicher immer mehr eine zentrale Rolle. Daher müssen ihr erfolgreicher Aufbau und ihr fehlerfreier Betrieb langfristig gesichert sein. Umfassende Kenntnisse der verwendeten Modelle, der verschiedenen Entwurfstechniken sowie der beim laufenden Betrieb zu beachtenden Maßregeln sind dazu notwendig. Das Buch widmet sich diesen Themen vor allem unter dem Aspekt der Datenbanknutzung. So kann der Praktiker die behandelten Konzepte und Techniken sofort anwenden. Ebenso bietet es Studierenden und Wissenschaftlern fundierte Information über aktuelle Techniken und Trends (verteilte datenintensive Anwendungen, Migration auf moderne Plattformen, Standardisierung).Drei durchgängige Anwendungsbeispiele ermöglichen den Vergleich unterschiedlicher Lösungsmethoden.

Automation is nothing new to industry. It has a long tradition on the factory floor, where its constant objective has been to increase the productivity of manufacturing processes. Only with the advent of computers could the focus of automation widen to include administrative and information-handling tasks. More recently, automation has been extended to the more intellectual tasks of production planning and control, material and resource planning, engineering design, and quality control. New challenges arise in the form of flexible manu­ facturing, assembly automation, and automated floor vehicles, to name just a few. The sheer complexity of the problems as well as the state of the art has led scientists and engineers to concentrate on issues that could easily be isolated. For example, it was much simpler to build CAD systems whose sole objective was to ease the task of drawing, rather than to worry at the same time about how the design results could be interfaced with the manufacturing or assembly processes. It was less problematic to gather statistics from quality control and to print reports than to react immediately to first hints of irregularities by inter­ facing with the designers or manufacturing control, or, even better, by auto­ matically diagnosing the causes from the design and planning data. A heav- though perhaps unavoidable - price must today be paid whenever one tries to assemble these isolated solutions into a larger, integrated system.
