For several reasons a database may not satisfy certain integrity constraints (ICs), for example, when it is the result of integrating several independent data sources. However, mo...
Since their beginning in constraint programming, set solvers have been applied to a wide range of combinatorial search problems, such as bin-packing, set partitioning, circuit desi...
We solve the problem of obtaining answers to queries posed to a mediated integration system un der the local-as-view paradigm that are consistent wrt to certain global integrity...
Global semantic integrity constraints ensure integrity and consistency of data spanning multiple databases. In this paper, we take the initial steps towards representing global se...
Abstract. We show how to specify and use the metadata for a virtual and relational data integration system under the local-as-view (LAV) approach. We use XML and RuleML for represe...
