Improving Data Quality: Consistency and Accuracy

Summary: CFDs model data consistency beyond traditional FDs to detect inconsistencies. Two heuristic repairs (static and incremental) for CFDs are NP-hard; experiments show effectiveness, with a statistical accuracy guarantee above a predefined rate and minimal user effort.
