Diagrams

• Use Case Diagrams: Use case diagrams are utilized for illustrating the "actors" of an application and the system. An example might be a library visitor interacting with the book hold part of the system. This is a high level illustration. Figure 1 shows UModel's interface for use cases:

• Class Diagrams: A class diagram shows classes and types in a system and how they interact. This is more of a code-level diagram that shows inheritance, class methods, and the like. Figure 2 shows a class diagram in UModel.

• Object Diagrams: Object diagrams highlight objects and their relationships. These are typically a subset of a class diagram and a deeper code-level one. Like the class diagrams, these show constructors, methods, and properties. Figure 3 is a UModel object diagram.

• Packages: These show model elements and their organization in packages, as well as how they relate to one another. They're more of a high level diagram highlighting how the application is packaged. See Figure 4.

• Component Diagrams: These show the components of an application and their interfaces. Also shows what interacts with these components, as you can see in Figure 5.

• Deployment Diagrams: These diagrams show the hardware, software, and middleware elements and how they interact with one another. Another high level view—but from the application and infrastructure perspective. Figure 6 shows how this diagram looks in UModel.
