Define "system."   :-)

Tends to be a fairly foggy concept in legacy systems.  Is that one system or six?

Always set the "Six Blind Men & the Elephant" context switch when stepping on to this merry-go-round.

As I've likely said... I first became interested in this issue in 1980 at a life insurance company that had loaded a data dictionary (aka metadata repository in current jargon) with their systems artifacts & found some 70 different names for the core concept "policy number."

Basic business/underwriting issue... "just how many policies has Mr Idehen bought from us?"  Easy question to ask... rather more difficult to answer accurately & consistently.

Somehow I don't sense this issue—what are ALL the names for the concept policy number—resonates with the SW domain.
