A new article discusses a variety of MDM implementation styles and advises how to choose the right style for your business. The first MDM implementation style is Registry Style: “In this implementation style, a central MDM Hub is created as a registry that provides the master entities by pointing to the various source systems. There is no central data repository, and data continues to reside in the source systems. Therefore, this registry provides a ‘virtual’ golden view of the master entity from the connected systems, by using data federation. For implementing this, the various source systems publish their data and the MDM Hub stores only the source system IDs (as Foreign Keys), and other important data values needed for matching.”
The next is Co-existence Style: “In this implementation style, a central MDM hub is created by physically consolidating relevant data from various source systems. The spoke systems (data sources) create and store their own data, and the central gold copy in the MDM hub is updated based on events. The master data in this case is usually not used for supporting the transactions in the source systems (as is the case with Transactional Style of MDM), but rather supports reporting, and referential needs.”
A third style is Transactional Style: “In this implementation style, a central MDM hub is created by physically consolidating relevant data from multiple sources in the enterprise and storing them in one centralized hub to create a single, master version. The master data is arrived at by linking, cleansing, matching and enriching data from various sources. The Hub is also responsible for enhancing and maintaining the master data and its attributes, over time.”
