    Study Notes

    Lecture 6: Design Modelling 1

    • The lecture is titled "How to create the representations of the software?"
    • Topics covered include Elements of Design Model, Data/Class Design, Architectural Design, and Architectural Concepts.
    • Design is the second task in the software development process, following analysis.
    • The design process involves translating the analysis model into a design model.
    • Design representations include data design, architectural design, interface design, and component-level design.
    • The different levels of design create a pyramid structure.
    • Data design creates a model of data, which is refined into progressively more implementation-specific representations.
    • Architectural design is derived from information about the application, requirements, data flow diagrams or analysis classes, and the availability of architectural patterns and styles.
    • Interface design describes externally observable behavior and access to public operations.
    • Interface components include user interface, external to other systems, and internal to other design components.
    • Component design describes the internal detail of each software component, including data, algorithms, and operations.
    • Component diagrams, activity diagrams, pseudocode (PDL), and flowcharts can be used for component design.
    • Deployment design describes how software functionality will be allocated within the physical computing environment.
    • Deployment diagrams can be of descriptor or instance form; descriptor form shows the environment without details, and instance form identifies specific hardware configurations.
    • The topics in the lecture further include data/class design, data structure design, architectural concepts, architectural considerations, architectural complexity, and architectural genres and styles.
    • Architectural description languages provide semantics and syntax for describing software architecture.
    • Agile methodologies facilitate architectural development through user stories and an evolving model, enabling better responsiveness and quality.
