UML Connectors

Notes:

• Invokes and Precedes relationships are defined by the Open Modeling Language (OML). They are stereotyped Dependency relationships; Invokes indicates that Use Case A, at some point, causes Use Case B to happen, whilst Precedes indicates that Use Case C must complete before Use Case D can begin.
• An Extension relationship shows that a stereotype extends one or more metaclasses. All stereotypes must extend either one or more Metaclasses, or another stereotype that extends a stereotype (that itself extends a stereotype, and so on).
• A Tagged Value relationship defines a reference-type (that is, RefGUID) Tagged Value owned by the source stereotype. The Tagged Value is named for the target role of this association, and is limited to referencing elements with the stereotype by the association target element.
• The Application and Redefinition relationships are deprecated.
