Realization is a specialized Abstraction dependency between two sets of NamedElements, one representing a specification (the supplier) and the other representing an implementation of that specification (the client).
To model a realization between two classifiers, you create a Realization Node, and connect the Classifiers to the Realization Node (see
Realization) through the
Realization Node to Client relationship and the
Realization Node to Supplier definition, respectively.
