Instantiating a Class means that the created Object has attributes associated with that type in the abstract model. For instance, the class “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
