In the context of data integration on the web, traditional data integration system lacks scalability, flexibility, is no longer adequate. A novel data integration architecture, UQSIQ, is proposed, which achieves web-scale data integration. Key components in the system are introduced. UQSIQ maps user query schema to a suitable domain, selects web databases, querys and then ranks results. Key techniques, domain mapping and user query schema matching, to handle the scale and heterogeneity of structured web data are described.
