ArchiMate defines 11 core relationships organized into four categories. Understanding proper relationship usage is critical for model quality and analysis.
Relationship Categories
Structural Relationships (Static Construction)
| Relationship | Notation | Usage |
|---|---|---|
| Composition | Solid line + filled diamond | Strong whole-part; parts cannot exist independently |
| Aggregation | Solid line + hollow diamond | Weak whole-part; parts may belong to multiple aggregations |
| Assignment | Solid line + circle at source | Who/what performs behavior; links actors to roles, components to functions |
| Realization | Dashed line + hollow triangle | Logical-to-physical mapping; cross-layer implementation |
