Data Quality for the CDMP Exam: Study Guide & Practice
For CDMP preparation, Data Quality is best learned as a set of decisions rather than a list of definitions. Focus on accuracy, completeness, validity, uniqueness, timeliness, root-cause analysis, quality rules, thresholds, and remediation. Practice should test whether you can choose the best action in realistic business situations.
- How should data quality rules become measurable?
- Why can aggregate quality percentages be misleading?
- How should teams prioritize and eliminate recurring defects?
