Extending Relational Query Optimization to Dynamic Schemas for Information Integration in Multidatabases

Summary: Extends relational optimization to dynamic schemas via FISQL/FIRA for multidatabases; enables runtime metadata and GAV/LAV/GLAV mappings. Bi-level optimization pushes subfragments to source engines; deployment on distributed multidatabases shows empirical feasibility. (summarized by gpt-5-nano on Feb 09 2026)
