Um Estudo e Proposta de Abordagem a respeito de Extração Semi-Automática de Restrições de Integridade Semântica de Dados XML

Khaue RodriguesRonaldo Mello

Web has been extensively used as a very large information source, as well as a vehicle for information interchange. However, data on the Web present high heterogeneity. Because of this, there is an increasing need for tools that are able to deal with such heterogeneity, like information integration tools. In this context, this paper presents a study about XML data integrity constraint management, and proposes an approach for semi-automatic extraction of semantic integrity constraints from XML schemata and XML instances. Such support provides better quality in XML data integration process as well as in the optimization of queries formulated over integrated schemata.
