Check your answer
Write your response and explain your reasoning.
Audit the three Cedar Trail revenue facts. Construct each complete identity key, identify true duplicates, explain why the product member changes identity, and list the evidence required for any extension.
Compare your reasoning with the worked answer
All three rows have complete structural keys. The first and third share the same complete identity, so there is one duplicate. The product-dimensional fact is distinct. Tag appropriateness and the accounting amount still require separate review.
