It is still not unusual for two tables to cross with a foreign key in each pointing to the other. Circular relationships are not rare. As another example,
a table of a publishers books can be linked with a table of the publishers authors (books have authors and authors write books).

They can be murder to load (chicken or egg type question) and maintain (deletes have the same problem), but they are not unusual. Received on Mon Nov 24 2003 - 21:39:50 CET
