US Patent 11403280 Master data management technologies

Disclosed embodiments are related to Master Data Management (MDM) technologies. Each DB entity (record) in component databases (DB) is represented as a judgment, and an MDM system unifies judgments obtained from the component DBs into a unified set of judgments. In the unified set of judgments, linkages are judgments asserting that particular DB entities from different DBs are the same/similar, and a golden record comprises field values describing each of the DB entities. In making judgments, the MDM system consolidates judgments (or records) describing the same subject into a single judgment, and performs updates to field values in a manner that does not violate referential integrity. Each update is associated with an MDM consistent state. Updates in the form of judgments are provided to the relevant component DBs, which are converted into serializable transactions associated with respective MDM consistent states. Other embodiments may be described and/or claimed.
