This book constitutes the refereed proceedings of the Second East European Symposium on Advances in Databases and Information systems, ADBIS '98, held in Poznan, Poland in September 1998.
The 25 revised full papers presented were selected from a total of 90 submissions and six extended abstracts within a special section. "East meets West." The papers are organized in topical sections on query languges, optimization, collaborative systems, schema integration, storage and version management, object systems, knowledge discovery and the Web, and systems design.

This volume presents the proceedings of the First International Conference on Applications of Databases, ADB-94, held at Vadstena, Sweden in June 1994. ADB-94 provided a unique platform for the discussion of innovative applications of databases among database researchers, developers and application designers. The 28 refereed papers were carefully selected from more than 100 submissions. They report on DB applications, for example in air traffic, modelling, maps, environment, finance, engineering, electronic publishing, and digital libraries, and they are devoted to advanced database services, as for example image text and multimedia modelling, fuzzy set based querying, knowledge management, heterogeneous multidatabase management, and intelligent networks.

The Third International Conference on Foundations of Data Organization and Algorithms has been organized by INRIA in Paris from June 21 to 23, 1989. Previous FODO Conferences were held in Warsaw, 1981, and in Kyoto, 1985. The goal of this year's conference is to present advances in techniques of permanent and temporary data organization in different fields. New applications such as image processing, graphics, geographic data processing, robotics, office automation, information systems, language translation, and expert systems have developed various data organizations and algorithms specific to the application requirements. The growing importance of these applications has created a need for general studies on data organization and algorithms as well as for specific studies on new database management systems and on filing services. The articles submitted for the conference were subject to the usual rigorous reviewing process and selected on that basis. They offer an excellent snapshot of the state of the art in the field and should prove invaluable for computer scientists faced by the problems of data organization which are raised by these new applications.
