Collaboration Diagrams

I l @ ve RuBoard

A collaboration diagram is an alternate way to show a scenario. This type of diagram shows object interactions organized around the objects and their links to each other. A collaboration diagram contains

• Objects drawn as rectangles

• Links between objects shown as lines connecting the linked objects

• Messages shown as text and an arrow that points from the client to the supplier

The UML notation for objects, links, and messages in a collaboration diagram is shown in Figure 5-10.
