- This article focuses on applying Unified Modeling Language (UML) Use-Case Diagrams in designing an online shopping system, emphasizing actors, use cases, and their relationships.
- UML Use-Case Diagrams play a crucial role in capturing functional requirements and illustrating user interactions within the system.
- Actors, use cases, and relationships are essential components of UML Use-Case Diagrams, providing insights into system functionality and behavior.
- Use case modeling involves identifying actors, which can be individuals or systems interacting with the system to achieve specific goals.
- Relationships in UML diagrams include associations, includes, extends, and generalizations to depict interactions between actors and use cases.
- The article includes an illustrative Use-Case Diagram for an online shopping system, showcasing actors, use cases, and their interconnections.
- Main actors, secondary actors, direct actors, and abstract actors are identified in the context of the online shopping system.
- Use case documentation aids in identifying actor-to-actor, actor-to-use case, and use case-to-use case relationships within the system.
- Examples of main flows and alternative flows in use case documentation demonstrate typical and exceptional user interactions with the system.
- UML Use-Case Diagrams provide a high-level overview of system functionality, while use case documentation details specific user interactions with the system.
