  • Parallel tables for data model with inheritance
    Patent number: 5418961
    Abstract: A parallel tables structure and method of implementation for an object-oriented data model are presented. The novel structure includes a plurality of memory tables separate from but associated with the object-oriented data model. Level-relative indices are initially arbitrarily assigned to each category such that an object in a particular category receives only one index for each supercategory in the object-oriented data model. These level-relative indices are used to locate a particular table in the plurality of memory tables which contains, for example, an attribute value (or relation) for an object in that category. The object's own index is used to retrieve the attribute value from the identified memory table.
