Generalization (2/2)
Properties of Generalization:
- non-complete / complete (default)
- complete: all possible subclasses are already part of the model (but not necessarily visualized!)
- overlapping / disjoint (default)
- 2 interpretations of overlapping:
- Concerning multiple inheritance: two or more subclasses can have again common subclasses (e.g. Instructor)
- Concerning multiple classification: an object can be instance of more than one subclass
