Adrian Onet. The Chase Procedure and its Applications in Data Exchange. In Data Exchange, Integration, and Streams. Dagstuhl Follow-Ups, Volume 5, pp. 1-37, Schloss Dagstuhl – Leibniz-Zentrum für Informatik (2013)


The initial and basic role of the chase procedure was to test logical implication between sets of dependencies in order to determine equivalence of database instances known to satisfy a given set of dependencies and to determine query equivalence under database constrains. Recently the chase procedure has experienced a revival due to its application in data exchange. In this chapter we review the chase algorithm and its properties as well as its application in data exchange.
