Architects debate issuing a new surviving enterprise party ID versus keeping each source key and maintaining a crosswalk. What is the sound guidance?
Select an answer to reveal the explanation.
Short Explanation
IDs are the name tags on the jackets—you can issue a city-wide tag, keep the old tags with a map between them, or do both on purpose. Blindly burning source keys loses the trail home. Pick the strategy; do not shrug.
Full Explanation
Identifier strategy is a core MDM architecture decision. An enterprise surviving ID simplifies consumer references; retaining source keys with a crosswalk preserves lineage and incremental integration. Many programs use both. Discarding source keys without a plan, assuming source keys alone are globally unique, or treating IDs as irrelevant undermines matching, integration, and auditability.
