Abstract This paper describes a method for the organization and retrieval of attribute based information systems, using the normal multiplication table as a directory for the information system. Algorithms for the organization and retrieval of information are described. This method is particularly suitable for queries requesting a group of information items, all of which possess a particular set of attributes (and possibly some other attributes as well). Several examples are given; the results with respect to the number of disk accesses and disk space are compared to other common approaches. Algorithms evaluating the appropriateness of the above approach to a given information system are described. For a certain class of information systems, the normal multiplication table method yields far more rapid retrieval with a more economical space requirement than conventional systems. Moreover this method incorporates an improved modification of the inverted file technique.
