Consolidation: A consolidated architecture moves data from various sources to a master repository. Consolidation usually occurs during scheduled batch process windows, but does not synchronize data with downstream sources within the master repository.
Registry: This type of MDM uses “stubs,” otherwise recognized as abbreviated records that include the data’s details, such as its location, source, or other information. It is also the fastest and most cost-effective architecture to implement because it consolidates stubs into a working repository and also reduces the amount of data moving through MDM tools.
Centralized: With this MDM architecture, master data is authored, then stored, and accessed when needed from MDM hubs, either in a transaction use case or in a workflow.
Coexistence: Unlike the consolidation or registry architectural approach, the coexistence style of MDM synchronizes master data back down to the sources. In turn, a master record is created in both the prime repository as well as at the individual system level.
