Frequent constraint violations on the data stored in a database may suggest that the semantics of the represented reality is changing. In this work we propose a methodology and a t...

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...

We study the problem of rewriting queries using views in the presence of access patterns, integrity constraints, disjunction, and negation. We provide asymptotically optimal algori...

Traditional methods for integrity checking in relational or deductive databases heavily rely on the assumption that data have integrity before the execution of updates. In this wa...

In this paper, we present an approach to query processing for paraconsistent databases in the presence of integrity constraints. Paraconsistent databases are capable of representi...
