内容説明
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.
