naming convention follower follow model
naming conventions for relationship tables
Yes, i searched for what other people chose for a naming convention for a table (model) of follower and followee relationships.
The only directly relevant discussion was in this Ruby on Rails tutorial, which settled on "Relationship". What we've been using, Followership, is better than that, i think.
Another take on relationships in Naming Standards for Data Models from Stanford University (in 1995) pronounces that the verb in the phrase describing the relationship should be used for the table name. It does make sense to just use the verb for relationship tables. Maybe next time!
