Tate is a data analyst at the Dion & Bidgood Real Estate Initiative. He is responsible for confirming that data in the initiative’s database is accurate or true. This responsibility is known as which of the following?
Correct Answer: b) Data verification
Data verification is the process of checking whether data in a database is accurate, consistent, and reliable by comparing it against source documents or predefined rules. Since Tate’s responsibility is to confirm the accuracy or truthfulness of the data, this aligns with data verification.
Incorrect Answers:
Data validation – Ensures that data is entered correctly and meets required formats before being stored in a database (e.g., checking if an email field contains a valid email address). Validation happens before data is stored, while verification checks after data is entered.
Quality Assurance (QA) – A broader term that covers processes and methodologies used to ensure the overall quality of data, software, or systems. It is not specifically about confirming data accuracy in a database.
Master data management (MDM) – A strategy for managing an organization’s critical data centrally, ensuring consistency across systems. It focuses on maintaining a single, unified view of key data rather than verifying individual records.
