MS Access relationships using MySQL ODBC

Hi,

I have an MS Access application with MySQL DB (ODBC), and would like to ask about the functionality of the DB relationships diagram in MS Access in this context:

I understand that it is quite helpful when creating new queries for creating joins automatically based on the relationships, but does it have any other functionality?

Thanks,

Here is a quick link which goes over some of the stuff you can do.

I'd also try the help in MS Access and MSDN for any other stuff.
