You can draw a query-to-query link (between two queries) if a foreign key in the detail table references the primary key in master table.
You can draw a group-to-group link (between two groups) if there are common columns in those groups. Don't touch columns, when you draw this kind of link!

Hi, Henrik:
It depends on the way you draw the link... :
Query-to-query
You can draw a query-to-query link (between two queries) if a foreign key in the detail table references the primary key in master table.
Group-to-group
You can draw a group-to-group link (between two groups) if there are common columns in those groups. Don't touch columns, when you draw this kind of link!
Column-to-column
You can draw a column-to-column link (between two columns) if there is a common column in those two groups.
Hope that helps.
Good Luck on your exam!
