DA0-001 · Question #325
A business unit made the following modification to the values in a table: Which of the following data quality dimensions was applied in this scenario?
The correct answer is D. Accuracy. The scenario describes a modification to data in a table, indicating an action taken to ensure the data's correctness. This directly relates to the data quality dimension of accuracy, which focuses on whether data values correctly represent real-world facts.

Why each option
The scenario describes a modification to data in a table, indicating an action taken to ensure the data's correctness. This directly relates to the data quality dimension of accuracy, which focuses on whether data values correctly represent real-world facts.
Integrity refers to the validity and consistency of data over its entire lifecycle, often enforced through rules like referential integrity, not merely by modifying values to reflect real-world correctness.
Consistency refers to whether data values across different datasets or over time are in agreement and do not contradict each other, which is different from correcting a single value's correctness.
Completeness refers to the degree to which all required data is present, without missing values, which is not the primary focus of modifying existing values.
Accuracy refers to the extent to which data correctly reflects the real-world events or objects it is intended to represent, meaning the data is free from error. When a business unit modifies values, it's typically to correct discrepancies and ensure the data precisely matches the actual state of affairs. This process directly improves the accuracy of the data within the table.
