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...
The Resource Space Model (RSM) is a semantic data model based on orthogonal classification semantics for effectively managing various resources in interconnection environment. In p...
The maintenance of global integrity constraints in database federations is still a challenge since traditional integrity constraint management techniques cannot be applied to such ...
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...
Integrity checking is aimed at efficiently determining whether the state of the information base is consistent after the application of a set of structural events. One possible way...
This paper addresses design exploration for protocols that are employed in systems with availability-consistency tradeoffs. Distributed data is modelled as states of objects repl...
We propose the Multiple Join Path (MJP) framework for obtaining high quality information by linking fields across multiple databases, when the underlying databases have poor qual...
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...
