Conjunctive Query Containment in Description Logics with n-ary Relations

Diego Calvanese, Giuseppe De Giacomo, and Maurizio Lenzerini

Proc. of the 10th Int. Workshop on Description Logics (DL 1997). 1997.

Recent research points out that query containment is a central problem in several database and knowledge base applications, including data warehousing, data integration, query optimization, and (materialized) view maintenance. In this paper we present a decision procedure for containment of conjunctive queries defined over a database schema specified in a very expressive description logic, comprising n-ary relations and general inclusion axioms on both concepts and relations.
