As far as I know, what is in ER modeling known as "role" cannot be automatically displayed on the relationship line. However, foreign keys should be marked automatically in the child table, provided the parent and child fields are properly connected in the relationship's definition.
I realize that this post is old, but just in case you have not found an answer: http://office.microsoft.com/en-us/visio-help/define-a-relationship-in-a-database-model-diagram-HA010115484.aspx#BM4 (Section Show relationships and their properties in a diagram).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
