I have some trouble transposing an ER-Diagram. I understand how to start but I am not sure transpose the diamonds for example the one say "contains" and how to go about the conductor. If I could get some advice it would be greatly appreciated.
So far this is what I have:
Concert Season(season_year*,closing_date,opening_date)
Concert(concert_number*, name,date,time)
Composition(composer_name,composition_name*,num_movements)
Member(city,state,zipcode,street,firstname,lastname,middle_inital,lastname,memberID*,musician,conductor)
Diagram is linked here: https://i.stack.imgur.com/jFRrv.jpg
