The three-letter acronym ADM stands, in a data management context, for Application Data Management.
Well, besides from that ADM is part of the word roADMap I see more and more signs of that the line between master data and other application data is blurring and Application Data Management will be part of the MDM roadmaps around.
The difference – and the intersection – between Master Data Management (MDM) and Application Data Management was examined here on the blog some time ago in the post called MDM vs ADM.
The pros and cons of seeing master data as something separate from any other data was also discussed in the post Master Data or Shared Data or Critical Data or What?
As also put forward then, I think it is useful to look at the data within the whole Enterprise Information Management (EIM) theme in lens of what is specific to your enterprise and what you have in common with other enterprises. Master data will typically be the data you share – or could share – with other enterprises, not at least your business partners.
In what degree do you find it useful to separate master data and other data in a MDM and/or ADM roadmap?
