Hi Omar how do we map a Mandatory Many to One relationship. The relationship is mandatory on both ends. We will not know if we have listed all the primary keys in the referenced table just by going through all the foreign keys in the referencing table. The above formula seems to work only if the relationship is optional on the many side.
