Two golden records appear for the same branch because legacy regional codes differ. How should matching be redesigned?
Select an answer to reveal the explanation.
Short Explanation
Regional keys can put the same branch in different buckets—like filing one person under two zip codes. Match across those legacy segments when the real-world entity is the same.
Full Explanation
Legacy regional segmentation often partitions true duplicates so same-segment rules miss them. Cross-region match design with appropriate controls is required; treating every regional code as a permanent entity, disabling matching, or randomizing keys worsens identity integrity.
