Meaning of Referential Integrity ("on parent update") Notation
When I create an ER diagram in Visio, and I have created a relationship, I
can select the "Referential Action" property under "Categories" and set it to one of the following: On parent update OR On parent delete No Action Cascade Set NULL Set default Don not enforce The notation displayed on the diagram is u:R d:R if I have "No action" selected. What does the "R" stand for?

Which version of Visio are you working with it might have some bearing on the
outcome. I tested with Visio Professional 2007 and I did not reproduce your results. -- James Wittrell Microsoft Support "ekreutzer" wrote: When I create an ER diagram in Visio, and I have created a relationship, I can select the "Referential Action" property under "Categories" and set it to one of the following: On parent update OR On parent delete No Action Cascade Set NULL Set default Don not enforce The notation displayed on the diagram is u:R d:R if I have "No action" selected.
