Object class ::= data type
Relational domain ::= data type
Object extent ::= unary relation
N-ary relation has no corresponding OO concept
Relational algebra/calculus has no corresponding OO concept
While there really is no such thing as a generally accepted "OO Data Model", most proposed OO Data Models are variants of the network data model with support for user-defined types. Received on Thu Jul 10 2003 - 00:00:34 CEST
