Study Notes
Business Process Modeling Notation (BPMN)
- Developed by the Business Process Management Initiative (BPMI) and later taken over by the Object Management Group (OMG).
- Aims to create a standardized notation for business processes that is understandable to both business and technical users.
- Facilitates communication and collaboration between stakeholders involved in process design, management, and implementation.
- Uses flowchart-like notation for easy understanding, bridging the gap between process design and implementation.
- Helps translate process designs into Extensible Markup Language (XML).
Elements in BPMN Diagrams
-
Flow Objects:
- Events: Start, modify, or complete a process. Can be throwing (sending an event) or catching (receiving an event). Includes various types like message, timer, error, compensation, signal, cancel, escalation, link, etc.
- Activities: Tasks performed by humans or systems. Can have sub-processes, loops, multiple loops, and compensation.
- Gateways: Decision points that adjust the process flow based on conditions or events. Types include exclusive, inclusive, parallel, complex, data-based, and event-based.
-
Connecting Objects:
- Sequence Flow: Shows the order of activities to be performed.
- Message Flow: Depicts messages flowing across pools or organizational boundaries, like departments. Should not connect events or activities within the same pool.
- Association: Links an artifact or text to an event, activity, or gateway.
-
Swimlanes:
- Pool: Represents a major participant in a process, like a company or department.
- Lane: Sub-division within a pool representing a specific role or participant, defining accountability for activities.
-
Artifacts:
- Data Object: Shows data required for an activity.
- Group: Logically groups activities, does not affect diagram flow.
- Annotation: Provides explanation for a part of the diagram.
Sub-Models within BPMN Diagrams
- Private Business Process (BP): Focuses on internal processes within a specific organization, without crossing pool boundaries.
- Abstract BP: Occurs between a private BP and an external participant or process, without showing the private BP's details.
- Collaborative BP: Depicts interaction between two or more business entities.
Unified Modeling Language (UML)
- A standard language for specifying, visualizing, constructing, and documenting complex software systems.
- Combines elements from Booch Method, Object-Modeling Technique (OMT), and Objectory.
- Primarily used by programmers, not database developers.
- Managed by the Object Management Group (OMG) for consistent usage across software development lifecycles.
UML Modeling Concepts
- Functional: Use case diagrams describe system functionality from a user's perspective.
- Object: Class diagrams define system structure in terms of objects, attributes, associations, and operations.
- Dynamic: Interaction diagrams, state machine diagrams, and activity diagrams describe internal system behavior.
Types of UML Diagrams
-
Structural UML Diagrams:
- Class Diagram: Defines the static structure of the system.
- Package Diagram: Organizes system elements into related groups.
- Object Diagram: Shows the static structure of the system at a specific time.
- Component Diagram: Organizes physical software components.
- Composite Structure Diagram: Depicts the internal parts of a class.
- Deployment Diagram: Represents physical system resources.
-
Behavioral UML Diagrams:
- Activity Diagram: Models the flow of control among activities in a system.
- Communication Diagram: Describes interactions between classes through message exchanges over time.
- Use Case Diagram: Models system functionalities using actors and use cases, representing a simplified collaboration diagram.
- State Machine Diagram: Describes a system's dynamic behavior in response to external events.
- Sequence Diagram: Models interactions between objects in a sequential order.
- Interaction Overview Diagram: Combines activity and sequence diagrams to model complex interactions.
- Timing Diagram: Focuses on processes over a specific period of time, with time increasing from left to right.
Architecture Description Language (ADL)
- Formal languages used to formalize, describe, and model software architectures.
- Provide abstractions for large and complex systems.
- Designed for users with technical backgrounds.
- Examples include UniCon, Wright, and Acme.
Important Properties of ADLs
- Representation of components through property assertions, interfaces, and implementations.
- Representation of connectors through protocols, assertions, and implementations.
- Abstraction and encapsulation of components and communication.
- Compatibility with analysis tools.
- Limiting communication to architecturally connected components.
- Modeling dynamic architectures.
- Reasoning about causality and time.
- Support for hierarchical refinement.
- Conformance checking.
Enterprise Architecture Layer Concepts
Motivation Concepts
- Model the reasons and enthusiasm driving enterprise architecture design or change.
- Influence, guide, and constrain the design process.
-
Terms:
- Stakeholder: Represents an interest in the architecture outcome.
- Driver: Internal or external condition motivating organizational goals and change.
- Assessment: Analyzes a business issue in relation to drivers.
- Goal: High-level statement of intent or desired end state for the organization.
- Requirement: Specific need that the architecture must meet.
- Constraint: Factor hindering or preventing the realization of goals.
- Principle: Qualitative statement linked to goals and requirements.
- Outcome: Achieved result.
- Value: Worth or importance of a core element or outcome.
- Meaning: Knowledge or expertise of a business object in a context.
Strategy Concepts
- Course of Action: Decision or plan an enterprise follows to achieve goals, configuring capabilities and resources.
- Capabilities: Key building blocks of a business, unique and stable over time. Achieve goals or deliver value through outcomes. Abilities possessed by a structure element (e.g., organization, person, system).
- Resources: Assets owned or controlled by individuals or organizations. Assigned to capabilities.
