Language Features for Interoperability of Databases with Schematic Discrepancies

Summary: Examines interoperability across relational DBs with schematic discrepancies; unified multidatabase views fail to reconcile metadata mismatches. Proposes Interoperable Database Language (IDL), a Horn-clause framework with higher-order data/metadata expressions and state-dependent multidatabase view definitions, plus complete view updatability.
