A county proposes an MDM style that only indexes pointers to resident records in source systems and does not materialize a composed set of attributes. How does this differ from a consolidation approach?
Select an answer to reveal the explanation.
Short Explanation
A registry is like a library card catalog—it tells you which shelves hold which books without rewriting the books into one mega-volume. Consolidation actually builds that composed golden record. Pointers alone are not the same as a materialized golden attribute set.
Full Explanation
Registry-style MDM maintains identifiers and links (and often match keys) that point back to source systems without necessarily assembling a full attribute-level golden record. Consolidation-style approaches materialize a composed master record from contributing sources under survivorship rules. The patterns are related but not interchangeable; choosing registry versus consolidation depends on whether consumers need a composed golden view or primarily a cross-system identity index.
