ABSTRACT:
Methods and apparatus are provided for detecting data inconsistencies. Methods are disclosed for determining whether a set of conditional functional dependencies are consistent; determining a minimal cover of a set of conditional functional dependencies and detecting a violation of one or more conditional functional dependencies in a set of conditional functional dependencies. The conditional functional dependencies comprise one or more constraints that data in a database must satisfy including at least one pattern with data values.
