Object Relationship Notation (ORN) is a declarative scheme that permits the semantics of a variety of relationships to be conveniently modeled and then defined to a Database Management System (DBMS), which then allows the DBMS to automatically enforce these semantics. The Unified Modeling Language (UML), which has gained much popularity since its beginning in 1994, provides another notation for describing the semantics of relationships. We have revised ORN to be compatible with this notation. This paper presents the new UML-compatible ORN.
