“system” might contain attributes such as information security or
performance whereas for the class “process” attributes such as efficiency
or cycle time could be appropriate. (The exact attributes of the classes as
well as what classes that are available is specified by the abstract model
(the theory) – developed in the EA2T Abstract Modeler.)
3.3 Instantiating relationships
Relationships are created between two classes and specify which relation
those classes have. Which relationships are valid is defined in the
underlying abstract model.
To create a relationship, press and hold the Ctrl key while dragging
between the classes. The order of source and target is not
