    Study Notes

    Business Process Modeling Notation (BPMN)

    • BPMN was developed by the Business Process Management Initiative (BPMI) and later taken over by the Object Management Group.
    • It provides a standardized notation for business processes, allowing for communication between business and technical users.
    • BPMN is designed to be used by stakeholders involved in designing, managing, and implementing business processes.
    • The notation is flowchart-like and independent of any specific implementation environment, creating a bridge between design and implementation.

    Element Types in Business Process Diagrams (BPMN)

    • Flow Objects:
      • Event: Trigger that starts, modifies, or completes a process. Includes types like message, timer, error, compensation, signal, cancel, escalation, link, etc.
      • Activity: Represents a task performed by a person or system. Can include sub-processes, loops, and compensations.
      • Gateway: Decision point that adjusts the path based on conditions or events. Can be exclusive, inclusive, parallel, complex, or based on data/events.
    • Connecting Objects:
      • Sequence flow: Shows the order of activities.
      • Message flow: Depicts messages flowing across pools or organizational boundaries.
      • Association: Associates an artifact or text to an event, activity, or gateway.
    • Swimlanes:
      • Pool: Represents major participants in a process, possibly from different companies or departments.
      • Lane: Sub-part of a pool, defining accountability within the process by showing activities and flow for a specific role or participant.
    • Artifacts:
      • Data object: Shows necessary data for an activity.
      • Group: Logical grouping of activities, but doesn't change the diagram's flow.
      • Annotation: Provides further explanation for a part of the diagram.

    Sub-Models within a BPMN Diagram

    • Private BP: Internal processes within a specific organization, not crossing pools or boundaries.
    • Abstract BP: Interactions between a private BP and an external participant or process, without showing the private BP itself.
    • Collaborative BP: Interactions between two or more business entities.

    Unified Modeling Language (UML)

    • Established as a standardized language for specifying, visualizing, constructing, and documenting software systems, both structurally and behaviorally.
    • Combines elements from the Booch method, Object-Modeling Technique (OMT), and Objectory.
    • Primarily used by programmers, not typically by database developers.
    • The Object Management Group (OMG) oversees its definition and maintenance.

    Modeling Concepts Specified by UML

    • Functional:
      • Use Case Diagrams: Describe system functionality from a user's perspective.
    • Object:
      • Class Diagrams: Describe the structure of a system using objects, attributes, associations, and operations.
    • Dynamic:
      • Interaction diagrams: Describe internal system behavior through state machine diagrams and activity diagrams.

    Types of UML Diagrams

    • Structural UML Diagrams:
      • Class diagram: Describes the static structure of a system.
      • Package diagram: Organizes elements of a system into related groups.
      • Object diagram: Models the static structure of a system at a specific time, testing class diagrams for accuracy.
      • Component diagram: Organizes physical software components, including source code, run-time code, and executables.
      • Composite structure diagram: Shows the internal parts of a class.
      • Deployment diagram: Depicts physical resources in a system, including nodes, components, and connections.
    • Behavioral UML Diagrams:
      • Activity diagram: Illustrates the dynamic aspect of a system by modeling the flow of control from activity to activity.
      • Communication diagram: Describes interactions among classes through message exchange over time.
      • Use case diagram: Models system functionalities using actors and use cases, serving as a simplified version of collaboration diagrams.
      • State machine diagram: Describes a system's dynamic behavior in response to external stimuli.
      • Sequence diagram: Models interactions between objects in a sequential order.
      • Interaction overview diagram: Combines aspects of activity and sequence diagrams for modeling complex interactions.
      • Timing diagram: Focuses on processes occurring within a specific time period, showing time increasing from left to right.

    Architecture Description Language (ADL)

    • Refers to formal languages used for describing and modeling software architectures formally.
    • A good ADL should provide abstraction for modeling large systems.
    • Different ADLs exist, each with distinct concepts and suitability for technically-oriented users.
    • Examples include UniCon, Wright, and Acme.

    Important Properties of ADLs

    • Ability to represent components, their properties (assertions), interfaces, and implementations.
    • Ability to represent connectors, including protocols, property assertions, and implementations.
    • Abstraction and encapsulation for components and communication.
    • Openness to accommodate analysis tools.
    • Limiting communication to architecturally connected components.
    • Modeling dynamic architectures.
    • Reasoning about causality and time.
    • Support for hierarchical refinement.
    • Ability to check conformance.
