An approach for the extensional integration of data sources with heterogeneous representation formats "
In this paper we deal with inconsistent databases and propose a logic framework that allows specifying sets of actions which should be performed to make databases consistent (repairs). The motivation of this work stems from the observation that in repairing a database it is natural to express among a set of update operations, the (preferred) actions which… (More)
The objective of this paper is to investigate the problems related to the extensional integration of information sources. In particular, we propose an approach for managing inconsistent databases, i.e. databases violating integrity constraints. The presence of inconsistent data can be resolved by " repairing " the database, i.e. by providing a computational… (More)
