This volume constitutes the proceedings of the 4th
International Conference on Database and Expert Systems
Applications (DEXA), held in Prague, Czech Republic, in
September 1993.
Traditionally the objective of the DEXA conferences is to
serve as an international forum for the discussion and
exchange of research results and practical experinece among
theoreticians and professionals working in the field of
database and artificial intelligence technologies. Despite
the fact that in the conference title the applications
aspect is mentioned explicitly, the theoretical and the
practical points of view in the field are well-balanced in
the program of DEXA'93. The growing importance of the
conference series is outlined by the remarkably high number
of 269 submissions and by the support given by renown
organizations. DEXA'93 is held for the first time outside
the former GDR in an East-European country, and is
essentially contributing to the advancement of the East-West
scientific cooperation in the field of database and AI
systems.
This proceedings contains the 78 contributed papers
carefully selected by an international program committee
with thesupport of a high number of subreferees. The volume
is organized in sectionson data models, distributed
databases, advanced database aspects, database optimization
and performance evaluation, spatial and geographic
databases, expert systems and knowledge engineering, legal
systems, other database and artificial intelligence
applications, software engineering, and hypertext/hypermedia
and user interfaces.
