Object Relationship Notation (ORN)tax, graphical representation, and semantics have changed slightly, and it has been integrated into UML class diagrams, adapted to relational databases, and applied to the development of all types of databases, not just scientific (Ehlmman and Riccardi 1994, Ehlmann and Stewart 1997, Neal and Ehlmann 2000, Ehlmann and Yu 2002, Ehlmann 2006).

ORN Simulatorototype database in the context of the model. This allows a database designer to observe, fine-tune, and verify the semantics, or behavior, of associations before implementing them in a real database application.

Object Relater , (OR+)tion is easier as database models more directly map to the required ODDL statements of OR+. More specifically, relationships can be defined with the multiplicities and bindings that are defined in UML class diagrams. These multiplicities and bindings are automatically enforced by the database system as database changes are made using ODML.
