th DEXA 2001, the 12 International Conference on Database and Expert Systems Applications was held on September 3–5, 2001, at the Technical University of Munich, Germany. The rapidly growing spectrum of database applications has led to the establishment of more specialized discussion platforms (DaWaK conference, EC Web conference, and DEXA workshop), which were all held in parallel with the DEXA conference in Munich. In your hands are the results of much effort, beginning with the preparation of the submitted papers. The papers then passed through the reviewing process, and the accepted papers were revised to final versions by their authors and arranged with the conference program. All this culminated in the conference itself. A total of 175 papers were submitted to this conference, and I would like to thank all the authors. They are the real base of the conference. The program committee and the supporting reviewers produced altogether 497 referee reports, on average of 2.84 reports per paper, and selected 93 papers for presentation. Comparing the weight or more precisely the number of papers devoted to particular topics at several recent DEXA conferences, an increase can be recognized in the areas of XMS databases, active databases, and multi and hypermedia efforts. The space devoted to the more classical topics such as information retrieval, distribution and Web aspects, and transaction, indexing and query aspects has remained more or less unchanged. Some decrease is visible for object orientation.

This volume constitutes the proceedings of the 4thInternational Conference on Database and Expert SystemsApplications (DEXA), held in Prague, Czech Republic, inSeptember 1993.Traditionally the objective of the DEXA conferences is toserve as an international forum for the discussion andexchange of research results and practical experinece amongtheoreticians and professionals working in the field ofdatabase and artificial intelligence technologies. Despitethe fact that in the conference title the applicationsaspect is mentioned explicitly, the theoretical and thepractical points of view in the field are well-balanced inthe program of DEXA'93. The growing importance of theconference series is outlined by the remarkably high numberof 269 submissions and by the support given by renownorganizations. DEXA'93 is held for the first time outsidethe former GDR in an East-European country, and isessentially contributing to the advancement of the East-Westscientific cooperation in the field of database and AIsystems.This proceedings contains the 78 contributed paperscarefully selected by an international program committeewith thesupport of a high number of subreferees. The volumeis organized in sectionson data models, distributeddatabases, advanced database aspects, database optimizationand performance evaluation, spatial and geographicdatabases, expert systems and knowledge engineering, legalsystems, other database and artificial intelligenceapplications, software engineering, and hypertext/hypermediaand user interfaces.
