Abstract

This invention relates to a method for operating a digital computer referencing a data base to derive from an explicitly selected subject a subset of subjects from data bases (indexed in, for example, the IBM Data Dictionary) needed to be selected for further processing based on the relationships of the subset to other previously selected subjects in the data base. This method may be applied to any collection of data that can be characterized in terms of types of data entities and relationships between those types in a data base environment, such as that provided by the IBM Information Management System (IMS). Each subject in the IBM Data Dictionary, hereinafter referred to as "the Dictionary", is an instance of a particular category of subjects.
