DA0-002 Data Concepts and Environments Practice Question
A data analyst needs to ensure that a customer's address is stored in a consistent format across multiple databases. Which data quality dimension is the analyst primarily concerned with?
⚠ Common exam trap
A common mix-up: candidates confuse consistency with accuracy, thinking that if the address is correct (accurate), it must be consistent, but consistency is about format uniformity across systems, not the truthfulness of the data.

Correct answer & explanation
✓
Consistency
The data analyst is primarily concerned with consistency, which ensures that the same data values are represented uniformly across different systems or databases. In this scenario, the customer's address must follow the same format (e.g., street, city, state, ZIP code) in every database to enable reliable merging and querying. Consistency is a key data quality dimension that focuses on cross-system uniformity, distinct from accuracy (correctness of values) or completeness (presence of all required fields).
