Abstract
An associative file design method and apparatus are used for automatically generating an integrated data base design structure, with minimal data redundancy, for use in multi-application general purpose digital computing systems. The integrated data base design structure is automatically produced by a programmed digital computer in the form of a report or graph structure which permits the data base designer to design a data base system with minimal data redundancy. The data needed by each application program, i.e., the local data view, is specified with certain constructs. The local data views are checked to ensure that specified rules are followed. The collection of local views is processed on a general purpose digital computer to separate 'keys' from 'attributes,' then to determine 'implied' and 'essential' associations, and finally to generate the integrated data base graph structure.
