问题


I have doubts in the following relationship:

An equipment consists of one or more products But one product can only be connected to that equipment and not another I came to this relationship, but I don't know if it is correct or I can improve if that way a product can only belong to one piece of equipment and one piece of equipment can have more than one product.
