Question 270
A direct relationship between two fact tables creates ambiguous results because both contain many repeated CustomerID values. What is the best method for this analysis requirement?
Explanation
Correct Answer
Shared one-side dimension keys control slicing of multiple facts without cross-grain joins; this helps repair fact-to-fact repeated key join.
Incorrect Answers
Explicit membership bridges capture many-to-many associations with defined keys. It would address segment membership modeling, not repair fact-to-fact repeated key join.
Bridges represent multiple associations while the measure controls distinct counting. That targets avoid duplicate product counts across tags, not repair fact-to-fact repeated key join.
Security membership bridges require carefully tested propagation paths. It is useful for many-to-many authorization membership, not for repair fact-to-fact repeated key join.
