Master Data Management with webMethods OneData : webMethods OneData Consolidation MDM Guide : Data Quality Data Objects : The Matching Process
The Matching Process
The matching process performs the following operations in the given sequence:
1. It retrieves records from the Consolidation table that are in the Cleansed state.
2. It determines if there is a matching record:
a. If a matching record does not exist, the process creates a record in the Gold table.
b. If a matching record exists, the matching process applies the survivorship rules and updates the existing Gold record with the relevant attributes from the record being consolidated.
3. Once matching is complete, it updates the record in the Consolidation table with the status corresponding to the action performed, either Create Auto, Create Manual, Linked Auto, or Linked Manual.
Before defining qualifiers for the Consolidation Gold object, you must define additional qualifiers for the Consolidation object at the object level.
Important:  
OneData does not invoke the consolidation process if the Consolidation object is a sub-type created in Nova mode or if the Consolidation object is marked as both a Consolidation object and Consolidation Gold object.
