Then it isn’t master data anymore; it’s just one field of a record of a commercial document. This is taking a long way around to the same point.

(Presumably no-one is trying to reference-count GC their RDBMS. If so, I wish them all the luck in the world.)

I'm not quite sure what "master data" means in English (a non-native language to me) but Wikipedia tells me that it's "data about the business entities that provide context for business transactions" (and lists examples that sound relevant for this situation to me). Based on that I'm inclined to think that this would qualify.
