Hi Michael, Thanks for your reply here!
I did indeed come across the discussions on the Ashwood sorter and circular dependencies. When you speak of a circular object graph and taking your A -> B ... -> A example I just wanted to clarify and confirm that your example is essentially as follows; Imagine these are the tables; A[id (primary key), b_id] B[id (primary key), c_id] C[id (primary key), d_id] D[id (primary key), e_id] E[id (primary key), a_id] And these the foreign keys; A.b_id - B.id B.c_id - C.id C.d_id - D.id D.e_id - E.id E.a_id - A.id -------------- The sort of cycle I might have is as follows; Person[id (pk), country_id, telephone_id] Telephone[id (pk), country_id, number] Country[id (pk)] Person.country_id = Country.id Person.telephone_id = Telephone.id Telephone.country_id = Country.id Do you think this counts as the sort of cycle that might cause this sort of dice rolling effect? Thanks again!
