This volume contains selected papers presented at the European Symposium on Programming (ESOP) held jointly with the seventeeth Colloquium on Trees in Algebra and Programming (CAAP) in Rennes, France, February 26-28, 1992 (the proceedings of CAAP appear in LNCS 581). The previous symposiawere held in France, Germany, and Denmark. Every even year, as in 1992, CAAPis held jointly with ESOP. ESOP addresses fundamental issues and important developments in the specification and implementation of programming languages and systems. It continues lines begun in France and Germany under the names "Colloque sur la Programmation" and the GI workshop on "Programmiersprachen und Programmentwicklung". The programme committee received 71 submissions, from which 28 have been selected for inclusion in this volume.

This volume comprises the proceedings of the Eleventh International Conference on the Entity-Relationship Approach held in Karlsruhe, Germany, October 7-9, 1992. It contains the full versions of all the 22 accepted papers selected from in total 64 submissions; in addition, the two invited talks by Scheer and by Tsichritzis and others are represented asfull papers and the two other invited speakers contribute extended abstracts. All the contributions describe original research related to theoretical or practical aspects of the Entity-Relationship Approach,reflecting the trend of recent years in a wide range of database research activities. In particular, the topics database design aspects, object-orientation, integrity constraints, query languages, knowledge-based techniques, and development of new applications are addressed.

This book contains a selection of research papers describing recent advancesin the theory of concurrent systems and their applications. The papers were all presented at the CONCUR '92 conference, which has emerged as the premiere conference on formal aspects of concurrency. The authors include such prominent researchers as R. Milner, A. Pnueli, N. Lynch, and V.R. Pratt. The results represent advances in the mathematical understanding of the behavior of concurrent systems: topics covered include process algebras, models of true concurrency, compositional verification techniques, temporal logic, verification case studies, models of probabilistic and real-time systems, models of systems with dynamic structure, and algorithms and decidability results for system analysis. A key feature of CONCUR is its breadth: in one volume it presents a snapshot of the state of the art in concurrency theory. Assuch, it is indispensible to researchers - and would-be researchers - in theformal analysis of concurrent systems.

The papers in this volume were presented at SWAT 92, the Third Scandinavian Workshop on Algorithm Theory. The workshop, which continues the tradition ofSWAT 88, SWAT 90, and the Workshop on Algorithms and Data Structures (WADS 89, WADS 91), is intended as an international forum for researchers in the area of design and analysis of algorithms. The volume contains invited papers by L.G. Valiant (Direct bulk-synchronous parallel algorithms), A.A. Razborov (On small depth threshold circuits), G. Gonnet (Efficient two-dimensional searching), and E. Welzl (New results on linear programming and related problems), together with 34 selected contributed papers. Contributions cover algorithms and data structures in all areas, including combinatorics, computational geometry, data bases, parallel and distributed computing, and graphics.

The papers in this volume were presented at the International Conference on Database Theory, held in Berlin, Germany, October 14-16, 1992. This conference initiated the merger of two series of conferences on theoretical aspects of databases that were formed in parallel by different scientific communities in Europe. The first series was known as the International Conference on Database Theory and the second as the Symposium on Mathematical Fundamentals of Database Systems. In the future, ICDT will be organized every two years, alternating with the more practically oriented series of conferences on Extending Database Technology (EDBT). The volume contains 3 invited lectures and 26 contributed papers selected from a total of 107 submissions. The papers are organized into sections on constraints and decomposition, query languages, updates and active databases, concurrency control and recovery, knowledge bases, datalog complexity and optimization, object orientation, information capacity and security, and data structures and algorithms. Two of the invited papers survey research into theoretical database issues done in Eastern Europe during the past decade.

The theme of this book is the potential of new advanced database systems. The volume presents the proceedings of the 10th British National Conference on Databases, held in Aberdeen, Scotland, in July 1992. The volume contains two invited papers, one on the promise of distributed computing andthe challenges of legacy systems by M.L. Brodie, and the other on object-oriented requirements capture and analysis and the Orca project by D.J.L. Gradwell. The following four parts each contain three submitted papers selected from a total of 36 submissions. The parts are entitled: - Object-oriented databases - Parallel implementationsand industrial systems - Non-relational data models - Logic programming and databases
