  This is a generic question. To the moderators, I wasn't sure where to place this.

  I mostly work in the BI space now.

  Is it common in the industry for the team managing an app or data source to maintain an ERD? The places I've worked in the past few years are no longer doing this. I'm just curious if my experience is an aberration.

  Thanks!

  In my experience, ERDs are common during the initial database design phase, but rarely maintained as changes are made.
