Data processing systems and methods are provided for correcting data inconsistencies within one or more databases and/or data repositories. In accordance with one implementation, a correction module is selected from a set of correction modules, and the selected correction module is configured to correct data inconsistencies of a solvable data inconsistency type. Data having an data inconsistency of the solvable data inconsistency type is identified within one or more databases or data repositories. If the selected correction module is unassociated with an obstacle data inconsistency type, or if the identified data not include an inconsistency of the obstacle data inconsistency type, then the correction module corrects the data inconsistency within the identified data.
