In the example below, the class diagram (on the left), describes the statement of the requirement above for the static model while the object diagram (on the right) shows the snapshot (an instance of the class diagram) of the course enrollment for the courses Software Engineering and Databa...
In software engineering, a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects. 在软件工程中,类图在统一...
For example, if we are worried about what happens when the track breaks, modeling the tracks would help us identify failure modes and possible recovery mechanisms. Sign in to download full-size image Figure 1.18. UML collaboration diagram for major subsystems of the train controller system. Let...

The arrows indicate dependencies: the View depends on the Model class to provide data, the Controller depends on the Model class for information about what to display and depends on the View class to do the drawing. This diagram is idealized: there would be several classes in the Model, ...

For example, some systems can be configured with 1–128 cores using exactly the same component. The user only has to provide a different value for the parameter for the number of cores, and the component code creates the cores and wires them up to the interrupt controller and memory using ...
The threshold distances used by the cross-slide interaction are shown in the following diagram. The PivotRadius and PivotCenter properties are used only when single pointer input is detected. They have no effect on multiple pointer input. The value for these properties should be updated regularly ...
