  2. Class diagram - Wikipedia

    en.wikipedia.org/wiki/Class_diagram

    In software engineering, a class diagram [1] 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. The class diagram is the main building block of object-oriented modeling.

  3. Sequence diagram - Wikipedia

    en.wikipedia.org/wiki/Sequence_diagram

    A sequence diagram shows, as parallel vertical lines (lifelines), different processes or objects that live simultaneously, and, as horizontal arrows, the messages exchanged between them in the order in which they occur. This allows for the graphical specification of simple runtime scenarios.

  4. Unified Modeling Language - Wikipedia

    en.wikipedia.org/wiki/Unified_Modeling_Language

    A diagram is a partial graphic representation of a system's model. The set of diagrams need not completely cover the model and deleting a diagram does not change the model. The model may also contain documentation that drives the model elements and diagrams (such as written use cases). UML diagrams represent two different views of a system ...

  5. Stereotype (UML) - Wikipedia

    en.wikipedia.org/wiki/Stereotype_(UML)

    In UML, become is a keyword for a specific UML stereotype, and applies to a dependency (modeled as a dashed arrow). Become shows that the source modeling element (the arrow's tail) is transformed into the target modeling element (the arrow's head), while keeping some sort of identity, even though it may have changed values, state, or even class.

  6. Dependency (UML) - Wikipedia

    en.wikipedia.org/wiki/Dependency_(UML)

    A UML link is run-time relationship between instances of classifiers, while a dependency is a model-time relationship between definitions. A typical uni-directional link requires the one instance to know about, and thus depend, upon the other, but this is not required. A uni-directional link only requires the possibility of navigation not ...

  7. UML state machine - Wikipedia

    en.wikipedia.org/wiki/UML_state_machine

    For example, Figure 1 shows a UML state diagram corresponding to the computer keyboard state machine. In UML, states are represented as rounded rectangles labeled with state names. The transitions, represented as arrows, are labeled with the triggering events followed optionally by the list of executed actions.

  8. Flowchart - Wikipedia

    en.wikipedia.org/wiki/Flowchart

    For instance, Kaoru Ishikawa defined the flowchart as one of the seven basic tools of quality control, next to the histogram, Pareto chart, check sheet, control chart, cause-and-effect diagram, and the scatter diagram. Similarly, in UML, a standard concept-modeling notation used in software development, the activity diagram, which is a type of ...

    Class diagram - a type of static structure diagram that describes the structure of a system by showing the system's classes, their attributes and the relationships between the classes. Classifier - a category of UML elements that have some common features, such as attributes or methods.
