Extended set theory is an effective method for describing the complex data structures needed to support large-scale data base applications. This paper describes the incorporation of the salient concepts of extended set theory into a general tool for the design and implementation of large-scale database systems. This tool is called a set processor. This implementation is based on the representation of sets of positive integers as bit strings and the application of the Cauchy/Cantor Diagonal Method.
