E-Book Overview
Database technology is currently being pushed by the needs of new applications and pulled by the oppor- tunities of novel developments in hardware and systems architecture. The invited paper, two panel sessions and 27 papers in this volume report on how the technology is currently extending. One broad area covered is extended database semantics, including data models and data types, databases and logic, complex objects, and expert system approaches to databases. The other area covered is raw architectures and increased database systems support, including novel transaction models, data distribution and replication, database administration, and access efficiency.

Foreword This is the second EDBT conference. The first took place in March 1988 in Venice and was such a success that it was decided to create a biannual event and hold the second also in "Venice. The intent in creating the conferences has been to provide an international forum appropriate for the exchange of results in research, development and applications which extend the scope of database technology. The conferences are designed to facilitate and extend communication among researchers and between academia and industry. They are also intended to be international level European conferences providing a high quality forum for the European database research community. The program committee received 175 papers. These cane from 28 different countries, the largest contributors being the USA, West Germany, France, Italy and the United Kingdom. A wide range of topics was covered, the most popular being object-oriented systems, database and AI, logic and databases, data structures and query processing. From these 175 papers, we had the difficult task of selecting 27 papers. We also selected an invited speaker, Carlo Zaniolo who addresses the issue of deductive databases and their transition from the technology development phase to the system implementation phase. Two panels were chosen to address some of the most burning issues of the field, the impact of theory on systems in the past and in the future, chaired by David Maier, and the two "competing" fields of object-oriented dat
