Heuristics and multi-dimensional physical database design: An experimental KBS

摘要

An expert system approach has recently been used for VSAM (Virtual Storage Access Method) file organisation [2]. This paper applies a heurestic approach to the process of selecting physical organisations for multi-dimensional (m-d) data. It analyses features of various access methods and using expert knowledge matches features for a range of m-d algorithms with corresponding characteristics of an application. This paper focus on the system design of the KBS. An example of the heuristic decision process is illustrated. How to deal with incomplete information is briefly discussed.
