Can't a doctor have multiple patients and a patient multiple doctors? Wouldn't the example mentioned then be of a many-to-many and not many-to-one type?

Well it seems to be correct there: there is a many-to-many example regarding doctors and patients and one-to-many between doctors and departments. Zeratul021 (talk) 21:12, 15 January 2009 (UTC)[reply]
