    Study Notes

    Keywords

    • Software: A set of instructions or programs that tell computers how to perform specific tasks.
    • Software Development Life Cycle (SDLC): The process of developing software from an initial idea to a finished product.
    • Server: A computer or program that provides data to other programs or computers.

    Software Development Life Cycle (SDLC)

    • Any software starts with an idea to solve a user problem.
    • This idea goes through a defined process called SDLC.
    • SDLC is a method that outlines the stages for producing high-quality software.
    • There are seven key phases in SDLC.

    Seven Phases of SDLC

    • Planning: The initial brainstorming and groundwork.
    • Requirements: Analyzing and documenting the needs of the software.
    • Designing and Prototyping: Creating the blueprint and a model of the software.
    • Software Development: Actual coding of the software.
    • Testing: Ensuring that the software functions as intended.
    • Deployment: Putting the software into use/into the market.
    • Operations and Maintenance: Ongoing operational support and improvements.

    Advantages of Using SDLC

    • Creates high-quality software.
    • Improves customer service.
    • Increases employee productivity.
    • Saves money.

    Team Roles in SDLC

    • Project Manager: Manages budget, resources, and timelines.
    • Business Analyst: Understands business needs and technical requirements.
    • Designers: Plan the design of the product and user interface.
    • Developers: Write the software code.
    • Operations: Sets up the hardware for the software.
    • Testers: Validate that the software meets the required quality.

    Requirement Analysis (SRS)

    • Requirement Analysis: Involves a detailed discussion with stakeholders on the project requirements.
    • SRS Report Outline: Includes sections for introduction, literature survey, functional and non-functional requirements, SDLC Model, feasibility study, system architecture, development, testing/results, and conclusions.
    • Functional Requirements: Define how the system works and responds to inputs.
    • Non-Functional Requirements: Define the system's quality, such as performance, scalability, security and usability.

    Design and Prototyping

    • The design phase analyzes the project's requirements and plans the product.
    • Designers often develop multiple design approaches.

    Design Phasese

    • System Design: Identifying modules and/ or pages that make up the system.
    • Detailed Design: Explains the logic associated with each module/page within the system.

    System Design Methodology

    • Designers can use abstraction methodology to break systems into smaller parts to better focus on one segment of the system at a time.

    Software Development

    • Developers write the code based on the project design.
    • Designers continue to plan the user interface.
    • Testers analyze requirements to create test cases.

    Testing

    • Testing validates the software's functionality and quality.
    • Errors found during testing are corrected before launch.
    • Testing helps in finding and avoiding software defects.

    Operations and Maintenance

    • Encompasses ongoing operations and support of the software to ensure continued functionality (and identify future improvements).
    • Includes: Performance, Feedback, Maintenance

    SDLC Models

    • Different models can be used to complete a software project, with each model having their unique approach to the distinct phases of the SDLC.
    • The choice of model depends on the customer's requirements and the timeline for project completion.
    • Examples: Waterfall model, Agile model.

    Waterfall Model

    • Documents requirements upfront.
    • Phases are completed sequentially.
    • Simple for understanding.
    • Suitable for projects with well-defined requirements.
    • Not flexible in handling changes in requirements.
    • Can be slow.
    • Difficulty handling large-scale projects.
    • Limited feedback availability.

    Agile Model

    • Adaptable to changing requirements.
    • Iterative approach.
    • Frequent feedback and testing.
    • Suitable for large-scale projects.
    • Requires extensive documentation (Agile methods support documentation but it is not usually a heavy part of an Agile project.)
    • Potential for time overrun if not properly managed.
