What is Structural Relationships?
Structural relationships represent the ‘static’ coherence within an architecture.
- The composing concept (the ‘from’ side of the relationship) is always an element;
- the composed concept (the ‘to’ side of the relationship) may in some cases also be another relationship.
Nesting Form of Elements
- Structural relationships may also be expressed by means of nesting of the composed concept within the composing element.
- However, that this can lead to ambiguous models, in case multiple structural relationships are allowed between these elements.
