In the last few months, more and more database-design questions have been migrated over here to dba. There is an entity-relationship tag over in SO. It's widely used, and I think usefully so. Should the same tag exist in DBA?
I know that I could create the tag if I wanted to, provided I have the rep. But I also want to avoid tag pollution. That's why I'm starting this discussion. The pros and cons of a new tag deserve an airing before a new candidate for burnination gets launched.
Edit: Somehow I missed the existence of erd yesterday. While there's a subtle difference between an ER model and an ER diagram, it's too fine a point to be worth worrying about. I'm deciding that, for now at least, the erd tag covers the necessary ground.
