Zenith Retail plc's management accountant finds that its sales dashboard shows the same customer under three slightly different names in separate regional databases, inflating the reported customer count. Which data quality dimension is most directly breached?

Uniqueness is breached. The same customer appears several times under slightly different names, which inflates the customer count. Timeliness, validity and completeness concern currency, permitted formats and missing values respectively, so they do not describe duplicated records of one entity.

  1. ATimeliness, because the data is out of date
  2. BUniqueness, because the same entity is recorded more than onceCorrect
  3. CValidity, because values fall outside permitted ranges
  4. DCompleteness, because mandatory fields are blank

Explanation

Duplicate records of one customer breach the uniqueness (no duplication) dimension. Timeliness concerns how current data is, validity concerns format or range, and completeness concerns missing values; none of these describes duplicated entities.
