摘要: A system, method, and program storage device implementing the for integrating data in a database management wherein method comprises grouping sources replicas of that provide analogous into common logical domain; writing application queries against selecting correct set query-execution strategy combining content order to answer according query-cost-based optimization; run-time constraints; shielding from changes by dynamically binding sets sources; processing generating an optimum query result based on steps shielding.
