If you modeled attributes that have been replaced by foreign keys, be sure to delete the modeled version of the attribute. a. TIP: If you don't see a foreign key in a related entity, double-click the relationship line to oper the Relationship Properties window, then close the relationship properties window. This should update the foreign key. Some foreign key additions are not automatically updated by the software. If you have questions about foreign keys, be sure to ask. Sometimes the relationship must be deleted and recreated after adding a primary key in order for the foreign keys to appear in the model.
