The trouble comes when a relation can have an attribute whose domain is a relation. Now there's an incestuous relationship between the relational engine and the type engine. The type engine has to know about relations, in order to be a type engine. The relational engine has to know about relations in order to be a relational engine. But do they each know that the other one also knows? Received on Wed Oct 27 2004 - 23:53:40 CEST
