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...
We consider the problem of retrieving consistent answers over databases that might be inconsistent with respect to some given integrity constraints. In particular, we concentrate o...
In order to deal with inconsistent databases, a repair semantics defines a set of admissible database instances that restore consistency, while staying close to the original insta...
Although integrity constraints have long been used to maintain data consistency, there are situations in which they may not be enforced or satisfied. In this paper, we present Con...
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...
