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.
