Term	Kind	Topic	What it is
Golden Record	concept	Master Data Management	The single authoritative version of an entity assembled from conflicting sources, and the survivorship rules that decide which value wins.
Master Data Management MDM, Golden Record	practice	Master Data Management	Establishing a single authoritative version of core business entities that appear inconsistently across many systems.
Match Confidence Band Match Threshold Band, Review Band	metric	Master Data Management	The score range between automatic merge and automatic reject in record matching, which is where a consolidation programme's permanent staffing cost lives and where its worst errors are prevented.
Survivorship Rules Golden Record Rules, Attribute Precedence	practice	Master Data Management	Per-attribute rules deciding which source's value wins when several systems hold a different value for the same entity - the part of master data management that determines whether the golden record is trusted.
Unmerge Capability Merge Reversal, Split-Back	pattern	Master Data Management	The designed ability to reverse an incorrect entity merge and restore both original records, which requires that source keys and pre-merge attribute values were never destroyed.
