With a UML use case diagram, you can create a broad, high-level view of the relationship between use cases, actors involved, and systems being performed.

The connected circles, or “lollipop” symbols, represent realization relationships within the systems. The component diagram examples below show the structural relations between components in an online shopping system, library management system, and an ATM system. Diagrams are structured this way so that the components can be easily replaced when needed. The components that make up this type of diagram are modular parts of the system that are inherently replaceable.

Both component and class diagrams display the structural relationship of software systems and their elements however, component diagrams generally simplify the interactions within more complex systems. UML Class Diagram for Online Shopping (Click on image to modify online) UML Class Diagram for Domain Models (Click on image to modify online) UML Class Diagram for Library Management Systems (Click on image to modify online)Ĭomponent diagrams in UML are very similar to class diagrams. From there, additional UML symbols are used to model the various interactions and objects involved within the process.
In our examples below, you'll find that each class shape is labeled with its name in the first row, the second row displays each attribute of the class on a separate line, and the third row displays each operation on a separate line. Software engineers and business professionals often choose class diagrams to map the structure of particular systems because they clearly display the various classes, attributes, operations, and relationships between objects. The class diagram is one of the most commonly used diagrams in UML, as explained in depth in our guide on class diagrams.
