Select an answer to reveal the explanation.
Short Explanation
Think of a credit-union table that still needs a stable customer key for joins, but must not carry the raw account number. Anonymize or tokenize it. The join still works. The raw number does not ride along.
Full Explanation
Replace raw identifiers with anonymized or tokenized keys while preserving join-ability. Keeping the raw number, dropping the key, and Polly are not that technique.
