Opis

This volume contains the 13 best of the 18 papers presented at the first MFDBS conference held in Dresden, GDR, January 19-23, 1987. A short summary of the two panel discussions is also included. The volume is intended to be a reflection of the current state of knowledge and a guide to further development in database theory. The main topics covered are: theoretical fundaments of the relational data model (dependency theory, design theory, null values, query processing, complexity theory), and of its extensions (graphical representations, NF2-models), conceptual modelling of distributed database management systems and the relationship between logic and databases.

O autorze

Joachim Biskup has been Professor of Computer Science since 1981 at the University of Dortmund, University of Hildesheim and University of Dortmund again. He has done research in recursion and complexity theory, information systems with an emphasis on database schema design, query optimization and mediation, and various aspects of security. He served on the program committees of many international conferences, including ICDT, FoIKS, ESORICS and IFIP WG 11.3 Conference on Database and Applications Security.
