Abstract
Systems, methods, and computer-readable media for evaluating data quality may include storing a plurality of records sharing a common attribute, and reading first values for the common attribute corresponding to a first time period and second values for the common attribute corresponding to a second time period. A business rule for evaluating the common attribute is accessed, and first and second consistency data are generated. The first consistency data may reflect consistency of the first values with the business rule at the first time. The second consistency data may reflect consistency of the second values with the business rule at the second time. The first consistency data and the second consistency data are processed to generate a quality change rate of the common attribute from the first time period to the second time period, based on the difference between the first consistency data and the second consistency data.
