    Learning Practice

  • 9.2.2

    System Design

    System Design is the phase of the Software Development Lifecycle (SDLC) where requirements are transformed into a detailed software architecture and design.

    Learning Practice

  • 9.2.3

    Implementation / Coding

    Implementation involves converting software design into actual source code.

    Learning Practice

  • 9.2.4

    Testing

    This section discusses the testing phase of the Software Development Lifecycle (SDLC), outlining its goal, types, and tools used to ensure software quality.

    Learning Practice

  • 9.2.5

    Deployment

    Deployment is the phase where the application transitions from development or testing environments to production.

    Learning Practice

  • 9.2.6

    Maintenance

    Sdlc Models

    SDLC models provide structured approaches for software development, ensuring adaptability to project needs.

    Learning Practice

  • 9.3.1

    Waterfall Model

    The Waterfall Model is a linear and sequential approach to software development, where each phase must be completed before the next begins, making it suitable for small, well-defined projects.

    Learning Practice

  • 9.3.2

    V-Model (Validation And Verification)

    The V-Model emphasizes validation and verification at every stage of the software development lifecycle, extending the Waterfall approach.

    Learning Practice

  • 9.3.3

    Iterative Model

    The Iterative Model focuses on developing software through repeated cycles of enhancement based on user feedback and evolving requirements.

    Learning Practice

  • 9.3.4

    Spiral Model

    The Spiral Model combines iterative development with risk analysis to create a structured yet flexible approach to software development.

    Learning Practice

  • 9.3.5

    Agile Model
