    Study Notes

    Unified Modeling Language (UML)

    • UML is a standard visual modeling language.
    • UML models software architecture, design, and implementation of complex systems both structurally and behaviorally.
    • UML is the most important industry-standard language for specifying, visualizing, constructing, and documenting software systems.
    • Three existing practices contributed to the development of UML: the Booch Method, Object-Modeling Technique (OMT), and Objectory.
    • The Object Management Group (OMG) oversees the definition and maintenance of the UML specifications.
    • UML enables engineers and programmers to use one language across all phases of the software development lifecycle.

    Modeling Concepts Specified by UML

    • Functional
      • Uses use case diagrams to represent system functionality from a user's perspective.
    • Object
      • Uses class diagrams to represent system structure in terms of objects, attributes, associations, and operations.
    • Dynamic
      • Uses interaction diagrams, state machine diagrams, and activity diagrams to describe a system's internal behavior.

    Types of UML Diagrams

    • Structural UML Diagrams
      • Class diagram: Describes the static structure of a system.
      • Package diagram: Used as a subset of a class diagram to organize elements of a system.
      • Object diagram: Describes the static structure of a system at a particular time.
      • Component diagram: Describes the organization of physical software components like source codes, run-time code, and executables.
      • Composite structure diagram: Shows the internal parts of a class.
      • Deployment diagram: Depicts the physical resources in a system, including nodes, components, and connections.
    • Behavioral UML Diagrams
      • Activity diagram: Illustrates the dynamic nature of a system by modeling the flow of control from activity to activity.
      • Communication diagram: Describes interactions among classes in terms of message exchanges over time.
      • Use case diagram: Models the functionalities of a system using actors and use cases.
      • State machine diagram: Describes dynamic behavior of a system in response to external stimuli.
      • Sequence diagram: Models interactions among objects in sequence.
      • Interaction overview diagram: Combines an activity diagram with a sequence diagram to model complex interactions.
      • Timing diagram: Focuses on processes taking place during a specific period of time, with time increasing from left to right.

    Architecture Description Language (ADL)

    Element Types in Business Process Diagrams

    • Swimlanes: Show who is responsible for each step
      • Pool: Represents major participants in a process. Different pools may be in different companies or departments.
      • Lane: A sub-part of a pool. Shows activities and flow for a certain role or participant, defining accountability within the processes.
    • Artifacts: Add extra details
      • Data object: Shows the necessary data for an activity.
      • Group: Shows a logical grouping of activities, but does not change the diagram's flow.
      • Annotation: Provides further explanation to a part of the diagram.

    Sub-Models Within A BPMN Diagram

    • Private BP: Involves internal processes specific to an organization and do not cross organizational boundaries.
    • Abstract BP: Occurs between a private BP and an external participant or process.
    • Collaborative BP: Shows interactions between two or more business entities.
