I am working on an event system that has two tables, EVENTS and EVENT_CREATORS. I have been linking events to creators by placing creator id in the events table as I thought I would only ever have one event creator.
I now need the ability for more than one creator to edit an event. Should I add simply add additional fields to EVENTS table, i.e ec_id, ec_id_2, ec_id_3, etc. Or does it make more sense to add a cross reference table to the database and a separate table for additional creators?
