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.
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.

Datenbanken spielen als Informationsspeicher immer mehr eine
zentrale Rolle. Daher mussen 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 uber aktuelle Techniken und Trends (verteilte
datenintensive Anwendungen, Migration auf moderne Plattformen,
Standardisierung). Drei durchgangige Anwendungsbeispiele gestatten
die Vergleichbarkeit unterschiedlicher Loesungsmethoden und machen
das Buch besonders wertvoll. Fur Wissenschaftler und Studierende
sowie Datenbank-Anwender und -Entwickler in Wirtschaft und
Industrie.
