Leveraging Query Logs for Schema Mapping Generation in U-MAP

Summary: U-MAP uses query-logs as usage signals to drive schema mappings, extending traditional mapping methods. It addresses mapping problems by exploiting schema workload data; tested on retail and life sciences datasets, with strong effectiveness and efficiency vs traditional approaches.
