How should I do this? Obj-1 <---[n:M]---> Obj-2 Obj-1 is in one table and Obj-2 is in a different table. The business rule is that a relationship must exist between two companies before there can be a link between Obj-1 and Obj-2. One company owns Obj-1 and the other company needs access to it via Obj-2. I can't think of any other way than to put two FKs to the Company table in Obj-2 and prevent Obj-2 being saved (raise a business integrity error) if there isn't a pre-existing relationship between the two companies. There is a Relationship table with one record for each pair of companies. If this is a reasonable thing to do? If so how would I tackle that in the save() method of Obj-2? Thanks for any ideas and pointers Mike
