UML Component Diagram for an Online Shopping System

A component diagram is useful for showing the structural relations between components. In some ways, these charts are similar to a class diagram, but they're able to show more complex relationships than a class diagram can. The “components” that make up this type of diagram are modular parts of the system that are inherently replaceable. Diagrams are structured this way so that the components can be easily replaced when needed. The component diagram example below shows the structural relations between components in an online shopping system. The connected circles, or “lollipop” symbols, represent realization relationships in the shopping system.
