Anyway, I think that rather than just adding unique to a column or set of columns that unique could be derived from a candidate key property somehow. (A candidate key being built on actual data values, rather than implementation pointers which is how primary and foreign keys are done in EO.)
This to me is one of the key differentiators between people that do O-R well and those who don't. The ones that don't think of FK and PK as the ways to access their data. For me, candidate keys is how one accesses one's data. The PK and FK are just there to hold the object tree/map/whatever together.
