Abstract
Human manipulation of objects generally includes handling knowledge concerning these objects. Knowledge handling requires in its turn the manipulation of documents. Document manipulation will be shown to require information transfer, storage and retrieval. When large amounts of information are to be stored and retrieved, the need arises for the creation of information storage and retrieval systems. This paper presents a description and design method for such systems. The method is based on a modelling technique. A logical system model will be shown to be derivable from the general objectives and the collection of tasks set for a system. It will then be explained how the physical realization of an information storage and retrieval system can be derived from its logical model taking account of hard- and software properties of the computer system and the programming language to be used. Finally a detailed outline will be presented for a design procedure. The practical applicability of this procedure has been proved during the design of several large data-base management systems.
