Data analysis using a geometrical representation of predicate calculus


This paper proposes an approach to database analysis and design, utilizing predicate calculus in the "infospace," i .e. in the space of the attributes. The difference B t Bz of two Boolean predicates in the canonical form, Br and Br , is discussed, and a geometrical representation is given in an n-dimensional space . A tabular method is derived to help in… (More)
