Improving the Use of Multiplicity in UML Association

By: Hee Beng Kuan, Yong Yang, Lei Bian


We propose a derived class and a derived association to improve the use of multiplicity for specifying business rules. In the use of n-ary association, if there is any business rule that can be expressed in terms of the number of instances of the association that associate each instance of an associated class or each combination of instances of k associated classes (1 < k < n-1), one from each class, we propose the inclusion of a derived class and/or a derived association.
