Uml Dependency. You can use dependency relationships in class diagrams component diagrams deployment diagrams and use case diagrams to indicate that a change to the supplier might require a change to the client. It is used in class diagrams component diagrams deployment diagrams and use case diagrams which indicates that a change to the supplier necessitates a change to the client.
Multiple components are established to form a relationship called tuples. Dependency is established within a range of elements that need other model components for the unique specification for implementation in uml.
