Association

To create an association relation between two elements, first select "Association" in the menu and after click on one element (class, actor or use case) of the relation, and after on the other element of the relation. The following DialogBox appears to fill information on the association relation.

The fields are the following:

In the Name Fields Area

  • The name
  • The stereotype.
  • The visibility (public, protected, private) .

    In each class Fields Area (fields from and to)

  • The role name : the name of the association_end, a value of the element linked (class, actor or use case) that behaves like an attribute.
  • The type (none, aggregate, composite).
  • The multiplicity.
  • Navigable flag : Indicates if an instance of the element (class, actor or use case) can 'traverse' the association.

    A click on the "ok" button generates the corresponding element in the Diagram Working window.
