Explanation

Redundant data refers to data that is duplicated or repeated unnecessarily within a dataset or across systems. Data redundancy is a common data quality issue that wastes storage space and can lead to inconsistencies when one copy is updated but another is not. Unique data means each record is distinct (the opposite of redundant). Unstructured data refers to data without a predefined format (e.g., emails, images). Incomplete data refers to missing values, not duplicated ones.
