Adapting to Source Properties in Processing Data Integration Queries
An effective query optimizer finds a query plan that exploits the characteristics of the source data. In data integration, little is known in advance about sources' propertie...

Load and Network Aware Query Routing for Information Integration
Current federated systems deploy cost-based query optimization mechanisms; i.e., the optimizer selects a global query plan with the lowest cost to execute. Thus, cost functions in...
