A unidirectional non-functional association is either one-to-many or many-to-many. In both cases such an association is represented, or implemented, with the help of a multi-valued reference property.

In this chapter, we show

  1. how to derive a JS class model from an OO class model with multi-valued reference properties representing unidirectional non-functional associations,

  2. how to code the JS class model in the form of JavaScript model classes,

  3. how to write the view and controller code based on the model code.
