Lambda Functions and Approximate Generalized Positive Boolean Dependencies

Abstract

The main purpose of the paper is to proposea lambda function and its apply to the concept of measurein comparing tuples of relations. Extend the generalizedpositive Boolean dependency to obtain a new type ofdependency called approximate generalized positive Booleandependency.The results can be applied in constructing more complicateddatabases, especially allowing extended search capabilitiesfor the real-world data.
