Abstract

A physical level design problem of record-to-area mapping is addressed in terms of an integrated data base design methodology. A problem of gathering record usage statistics, as a prerequisite of the record-to-area mapping, is discussed. Then a stepwise heuristic algorithm for the record-to-area mapping in the CODASYL data base environment is proposed and illustrated by an example. An iterative character of the algorithm and a necessity for design refinements and feedbacks are exposed.
