Well, there is the ability for a data model to represent attribute inheritance and this would involve a one-to-one parent to child, although it would need to be one way. An equity could could get its id from a financial instrument table and all financial instruments could inherit some particular attribute or relationship of that financial instrument, from the financial instrument table.

If this guy truly wants a one-to-one, yeah, that's a bad idea cause its the same damn table!
