Title:   Data Quality Analysis of Mutual Constraint Violations

Abstract/Description:
The CCICADA Data Quality team performed an in-depth data quality analysis of a customer database. The team defined a set of complex domain specific data quality constraints and identified violations in a set of 5 samples of data. This talk will report on a small follow-on study which analyzed the mutual constraint violations. The is provides a data quality attribute for each data item and  enables histogram data quality summaries for each query and data sample. Unique multi scale statistical parameters were computed to statistically characterize the histogram distributions for each sample. They are visualized by colorful day wheels to enable cognitive recognition of the difference in data quality between the samples. The method is general and could be applied to any data set described by a set of binary features.
