A question, "How to Model Inheritance of Two Tables MYSQL" was migrated to this forum from Stackoverflow. Unfortunately, my answer to that question contained references to three tags that do not exist (yet) in this forum.
The "info" tab on those three tags contained the nitty-gritty details concerning three techniques that I consider helpful to the asker. Those three tag references are now orphans.
What's the right solution? Is it replicating the three tags over here, and filling in the info tab with the same info? That seems like a violation of DRY (aka "harmful redundancy"). Is it plugging the details about the three techniques into the answer itself? That's also a violation of DRY. Is there a way of making a tag reference point to the tag in its original location? Is that a good idea?
I haven't had this much fun since the last time I tried to shuffle records in a pre-relational database (little joke).
As a side issue, I have to wonder why the question was migrated off of SO. Anybody who has done both object modeling and data modeling realizes that there is an enormous overlap between the two disciplines. That's notwithstanding the infamous "object relational impedance mismatch". I don't see how a moderator could consider object modeling questions on topic in SO but data modeling questions off topic.
