In Visio 2007, I can only seem to set the cardinality of the Parent-to-child relationship, but I want to set the Child-to-Parent as well. Is there a reason Visio won't let me do this? Do I need to create a separate relationship to achieve this? I'm using two Entity objects/shapes and a Relationship object/shape.
Note: I got the cardinality to appear on the diagram by going Database > Options >> Document and checking the Cardinality box.
From Menu; Database > Options >> Document
Click Relationship Tab. You will see Name Display. Check "show verb phase". Choose "Foward text", "Inverse text" or both.. That depands on your wish.
