You might know that Association relationship is a structural relationship which one of the classes knows about the information in another class But if you can please tell an example that I can understand it and I need to know about Realization relationship with an example ,too . I will appreciate you if you can tell some examples.

In the UML Specification by OMG defines Realization as below:

Realization is a specialized abstraction relationship between two sets of model elements, one representing a specification (the supplier) and the other represents an implementation of the latter (the client). Realization can be used to model stepwise refinement, optimizations, transformations, templates, model synthesis, framework composition, etc.

Also as specialized classes, there are ComponentRealization, InterfaceRealization, Substitution and InterfaceRealization is the most useful one for designing the programs.

An InterfaceRealization is a specialized Realization relationship between a Classifier and an Interface. This relationship signifies that the realizing classifier conforms to the contract specified by the Interface.

  • thank u but if it is possible describe it more on your diagram?? – Neda Feb 06 '15 at 07:22
  • This diagram represents that "DiagramElement Class" implements Resizable and Movable Interfaces. Dotted line is an InterfaceRealization. – Satomi Feb 12 '15 at 07:07
