The building next to my home office was originally two cement silos standing in an industrial harbor area among other silos. These two silos are now transformed into a connected office building as this area has been developed into a modern residence and commercial quarter.
Master Data Management (MDM) is on similar route.
The first quest for MDM has been to be a core discipline in transforming siloed data stores within a given company into a shared view of the core entities that must be described in the same way across different departmental views. Going from the departmental stage to the enterprise wide stage is examined in the post Three Stages of MDM Maturity.
But as told in this post, it does not stop there. The next transformation is to provide a shared view with trading partners in the business ecosystem(s) where your company operates. Because the shared data in your organization is also a silo when digital transformation puts pressure on each company to become a data integrated part of a business ecosystem.
A concept for doing that is described on the blog page called Master Data Share.

Thanks, this is a useful analogy and it’s nice to have links direct to your past content. This post helps explain some potentially very abstract concepts, and I hope it’s seen by any newcomers to this area of research.
