The Design and Implementation of CoBase

Summary: CoBase merges knowledge-base reasoning with relational DBs to deliver cooperative, approximate query answering via concept hierarchies—generalization, specialization, association. CSQL extends SQL with cooperative operators; a modular protocol and LOOM-based implementation on a Transportation DB show feasibility and adoption in UCLA's medical distributed DB.
