Bridge table question Should be a simple questions, I just want to make sure.

If I had 2 tables I want to bridge, for example food (food_id, foodname, ...) and a plate (plate_id, platetype, ..). When the tables are bridged, would they need to be foreign keys to each other or it wont be necessary as there is a food_plate table with food_id and plate_id ?

Thanks for the help
You will indeed want a third table (food_plate) with two foreign keys, food_id to the food table and plate_id to the plate table. The food and plate tables should not reference each other.
