Letter from the Co-Chairs

The East European Symposium on Advances in Databases and Information Systems (ADBIS) - a series of annual high quality international conferences - will provide a forum for the exchange of scientific achievements between the research communities of Eastern Europe and the rest of the world in the area of databases and information systems. It continues and consolidates the series of ADBIS workshops organized by the Moscow ACM SIGMOD Chapter and the East-West Database workshops.

The new annual Symposium will be hosted by different countries of the Eastern Europe including the Czech Republic, Estonia, Latvia, Lithuania, Poland, Russia, Slovakia, Slovenia, and Ukraine.

ACM SIGMOD will actively support the organization of the Symposia and warrant the high quality of the program. The Moscow ACM SIGMOD Chapter serves as a focal point of the event. The organizers have the ambition to make the ADBIS Symposium the premier database and information systems conference in Eastern Europe, to increase interaction and collaboration between researchers from East and West and to provide an internationally recognized tribune for the presentation of research.

The First East-European Symposium on Advances in Databases and Information Systems ADBIS'97 is aimed at bringing together researchers, practitioners, developers, and users to explore new concepts, tools and techniques for database management and their use in information management applications.

The symposium will last four days, the program of each day being organized in sessions. Registration will take place at the conference site, where attendees will also receive proceedings. A reception and business lunches will serve as social events.

We have an interesting and attractive agenda consisting of a keynote speech, tutorials, panels and paper presentations scheduled for the symposium. We plan to have a special session(s) to discuss the research activity of the Russian Foundation for Basic Research (RFBR) grant holders.

We welcome you to the Symposium. We are confident you will find exciting and thoughtful discussions of principles and practices of future information systems, innovative information technologies and presentations.

RFBR Plenary Address

The RFBR policy in the research and education infrastructure development.

Time: Tuesday, September 2nd, 15:30

The current dramatic changes taking place in the area of information industry, especially in forms, methods and scale of the information processing, enforce the intensive changes in researches, education and economy. According to the UNESCO data, more then a half of employees of the industrial countries are involved (directly and/or indirectly) into information production and distribution. Since the middle of 80-ies the labor productivity in the information field becomes a key factor of increasing the productivity in industrial countries; and the production efficiency of goods and services offered by science consuming branches for industrial exploitation of the national information resources (first of all in sci-tech field) becomes one of the most important feature of the economic development in such countries.

There is a stable tendency of steady piping of labor resources into the information generation and production area. National information resources become a new economic category.

Abstract. In this paper we discuss the management of semi-structured data, i.e., data that has irregular or dynamically changing structure. We describe components of the Stanford Tsimmis Project that help extract semi-structured data from Web pages, that allow the storage and querying of semi-structured data, and that allow its browsing through the World Wide Web. A prototype implementation of the Tsimmis system as described here is currently installed and running in the database group testbed.

ADBIS'97 Tutorials

Tutorial I:

>From parallel databases to distributed data management in high performance networks: a new challenge for database research

Lionel Brunie
    LIP -- CNRS at ENS Lyon
    69364 Lyon Cedex 7, France
    lbrunie@lip.ens-lyon.fr
Time: Wednesday, September 3rd, 9:30

Originally created for managing high performance applications, parallel computing is now mature for entering in everyday life. We believe the future of parallelism in general and parallel databases in particular is in little and medium size systems. Indeed such systems propose an optimal ratio price/performance. With the emergence of high performance networks, this ratio is even better. Indeed, high performance networks (ATM, Myrinet, IPv6, etc.) propose cheap, generic and extensible architectural solutions.

In fact, this technology allows parallelism to enter in everyday life "clandestinely'' as it transforms networks of workstations or PCs into de facto parallel machines. Some applications traditionally addressed by medium size monoprocessor servers, e.g. video on demand systems, documentary databases, intranet databases, CAD systems, etc. seem particularly well designed for a parallel implementation on high performance local networks. Furthermore, in the perspective of the implementation of high performance wide area networks (e.g. optical fiber), some distributed applications will become candidates for a parallelization, i.e. some operations, presently done using classical distributed methods, will be done using parallel implementation strategies.

However using a high performance network as a parallel database machine is not completely straightforward. Some specific problems have to be addressed from the query optimization to the resource allocation ; from the communication protocols to the DBMS administration.

"Transforming'' networks of workstations or PCs into parallel machines is certainly one of the most exciting challenge nowadays ! In that perspective, the goal of this talk is twofold. First, analyze what applications can benefit from the emergence of those networks. Second identify what problems are to be solved and what paradigms can be applied.

Tutorial II:

Workflow Management Systems

Johann Eder
    Department of Informatics,
    University of Klagenfurt, Austria
    eder@ifi.uni-klu.ac.at
Time: Thursday, September 4th, 9:30

Workflow management is one of the hottest topics in information systems today - in industry as well as in research. There are 100+ workflow management systems on the market already and analyst predict an enormous increase of the number of installations in the coming years. Most scientific conferences in the area of databases, information systems have sessions on workflow systems and the research groups and projects in this area are numerous. Workflow systems are designed to support the definition, execution, monitoring and managing of business processes. Current workflow management system provide quite different functionalities ranging from documented traceable email-based systems to high performance distributed advanced transaction management.

In this tutorial we will introduce the basic ideas and concepts of workflow systems, provide some classifications of workflow systems with respect to the business processes they support on one hand and on the type of functionality they provide. We discuss principle architectures of workflow systems and the typical components. In some detail we present the concepts of the workflow management system Pantha Rhei and its principle design decisions. Furthermore, we will give an overview of current research topics in the area, such as process management, workflow transactions for fault-tolerant workflow execution and workflow interoperability.

Instructor

Johann Eder received the degrees of Diplom-Ingenieur and Doctor of technical sciences from the University Linz, Austria. From 1985 till 1990 he was assistant professor at the University Klagenfurt. In 1990 he was visiting professor at the University of Hamburg and was then appointed as associate professor at the University Vienna. Since 1991 he holds the position of a full professor for information and communication systems at University Klagenfurt and since 1994 he is chairman of the Department of Informatics. The research interests of Prof. Eder include databases, information systems and knowledge engineering. Current research projects include workflow management systems, workflow transactions, views for object-oriented databases and object-oriented conceptual modeling. He authored/coauthored more than 50 papers published in international journals and conference proceedings and one book and co-edited two conference proceedings. He served in several program committees for international conferences and as referee for journals and conferences.
