6 Class Diagram

Grails controllers, domain classes and services have dynamic methods and properties that
won’t be depicted on the previous class diagrams in order to keep them clear. For
example, controller classes provide methods such as render and redirect to deal with the
application flow, and domain classes provide methods such as find, get, save and delete
to deal with persistence. [11]
