Object Role Modeling
     
         (ORM) A conceptual {model}ling approach that
        pictures the application world as a set of {objects} that play
        roles (parts in relationships, which may be unary, binary or
        higher order).  ORM provides both graphical and textual
        languages that enable models to be expressed naturally.  For
        {data modelling} purposes, its graphical language is more
        expressive than {ER} or {UML}.
