In this section, you will see how to insert new associations in your classes from the class diagram graphical interface.
To create an association, select the Association toolbar
button then click in the original class.
We suppose that you have previously created another class named "Address".
Select Association in the top down menu.
Drag and drop the association to the class
named Person", then click on the class, and move the other end of the
association to the class named Address.
Click on the class named Address and
release the mouse button.
