Please Help turn this UML diagram into an ER diagram, use tools like draw.io or similar for designing the ER so I can better learn plz. My end goal is to take this ER diagram and translate it onto Postgres as a relational database. Any help and insight in this regard would also be appreciated.
We must associate Camper with Session independently of the camper's Unit, because not all Campers are assigned to Units, and we still need to know which Session such a Camper is attending. We have a many to many with history between Rotation and Activity. An Activity can be scheduled during many Rotations; and many Activities can be scheduled during each Rotation. It is with history so we can have the same Activity scheduled during the same Rotation more than once; perhaps there is more than one Archery station, for example, and two Units can participate at separate Archery stations. There is no penalty in the rubric for doing this association without history, however.
