A utility requires that every meter reading reference an existing meter ID in the asset register. Which type of data quality rule is this?
Select an answer to reveal the explanation.
Short Explanation
A reading that points at a meter that does not exist is an orphan ticket—nobody can service it. Referential integrity-style rules keep child facts tied to real parents. That is integrity, not just spelling.
Full Explanation
Integrity rules enforce relationships expected between datasets, such as foreign-key existence. Requiring each meter reading to reference a known meter ID is a referential integrity expectation treated as a DQ rule. Violations produce orphans that break operations and analytics.
