Consistent query answering is the term commonly used for the problem of answering queries on databases that violate certain integrity constraints. We address this problem for univ...
A database D may be inconsistent wrt a given set IC of integrity constraints. Consistent Query Answering is the problem of computing from D the answers to a query that are consist...
In this paper we consider the problem of the logical characterization of the notion of consistent answer in a relational database that may violate given integrity constraints. Thi...
