Here we have many to many relationship between tour and places .
So Visual paradigm automatically add the bridge table but i want to keep Place Column two time as a foreign key in Tour_place table, Place_start (fk) Place_destination (fk) both referencing to the same column place for Place table.
I can easily create a table in oracle sql with both of them as foreign key but i also need to show both as a foreign key in ERD.
Just add a another relationship association line , now both Place_start and Place_destination reference the Pk places from Places table.
