Object Role Modeling
Jump to user comments
programming (ORM) A conceptual modelling 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.
