    Study Notes

    Software Development Process Models

    • Code-and-fix model: An early approach with only coding and fixing bugs; led to poorly structured code and expensive fixes. Highlighted the need for design and requirements phases.
    • Prototype model: Involves quick design, prototype creation, customer evaluation, requirements refinement, implementation, testing, and maintenance. Iterative process focusing on early customer feedback.
    • Spiral model: An iterative model incorporating risk analysis at each iteration. (Specific details from the referenced document are absent.)
    • Incremental development: Begins with initial specification and an initial version. Subsequent iterations build upon previous versions until the final version is achieved.
    • Test-driven development: A model where tests are written before the code.

    Agile Software Development Manifesto

    • Prioritizes individuals and interactions over processes and tools.
    • Values working software over comprehensive documentation.
    • Emphasizes customer collaboration over contract negotiation.
    • Favors responding to change over following a plan.

    Software Development Activities

    • Architectural design: High-level design of the system.
    • Component design: Design of individual components.
    • Persistence design: Design of data storage and retrieval.
    • Interface design: Design of user interfaces and interactions with other systems.
    • Component testing: Testing individual components.
    • System testing: Testing the entire system.
    • Customer testing: Testing by the end-user.
    • Deployment: Moving tested code into the production environment.
    • Documentation: Essential for future maintenance and enhancement, especially for external interfaces.
    • Software training and support: Crucial for successful software adoption.

    Building vs. Growing Software

    • The "building" metaphor likens software development to construction, implying detailed planning upfront.
    • "Growing" software starts with a minimal, functional system and adds features iteratively.

    DevOps

    • Why DevOps? Addresses the misalignment of goals between developers and operators.
    • What is DevOps? A set of practices aimed at improving collaboration between development and operations teams.
    • DevOps Practices: (Specific practices are not detailed in provided text)
    • DevOps Consequences: (Specific consequences are not detailed in provided text)
