    Study Notes

    Understanding UML

    • The learning outcome involving applying knowledge of UML is using UML diagrams to model software systems.

    Use Case Diagrams

    • System boundary: Represents the dividing line between the system and its external interactions.
    • Actors: Roles played by entities external to the system.
    • Use cases communicate the system's functionality from a user perspective.
    • Components NOT included in a use case diagram: System classes.
    • Use cases omit internal system details and implementation specifics.
    • Relationships NOT typically found in a use case diagram: Generalization.
    • Primary role of use cases: Identifying system requirements and user interactions.

    Software Development Models

    • Prototyping Model advantage: Enables early user feedback and validation.
    • Incremental Model suitability: Projects requiring early releases of functional components.
    • Prototyping Model drawback: Potential risk of developing a non-robust final product.
    • Prototyping Model usefulness: Exploring system feasibility and gathering user requirements.

    Use Case Components

    • Main scenario: Describes the typical, successful flow of events.
    • Not included in a use case's flow of events: Class diagrams.
    • Primary goal of Prototyping Model: Quickly create a working model to demonstrate system functionality.
    • Purpose of alternative flows: Handling exceptions, variations, and error conditions.
    • Prototyping Model benefit NOT included: Detailed documentation and documentation from the start.
    • Use case template section focusing on the goal: Purpose.
    • Key reason for choosing Incremental Model over traditional models: Reduced risk and early feedback.
    • Information NOT in the use case template: Detailed design considerations.
    • Prototype delivery to customer: Provides a tangible representation of the system for feedback.

    Library System Use Cases

    • Action before reserving books: Member must authenticate.
    • 'Extend' relationship meaning: Adding optional behavior to a base use case.
    • Base use case in an extend relationship: The main, core functionality.
    • Linking 'Enroll In Uni' and 'Perform Visa Check': Include relationship.
    • Customer action in SLIIT Library System: Searching for books and paying fines.
    • Include relationship definition: Adding a common piece of functionality to multiple use cases.
    • Validating user in library system goal: Authenticating and authorizing access.
    • Typical content of a use case diagram: Identifying core functionality and system interactions.
