Study Notes
SDLC
- Software Development Life Cycle is a systematic approach to developing high-quality software that meets business requirements.
- Consists of phases of development, each with its own process and deliverables.
- It is a cycle of planning, designing, and development that can be implemented iteratively.
- Benefits of the SDLC include minimized cost and risk, ensuring the correct product is created, high quality, improved efficiency, and facilitates communication through discrete phases and iterations.
Phases
- SDLC Phases include:
- Planning: Gathering requirements, initial user interface, technology selection, technical architecture, project plan, and
- The Software Requirements Specification (SRS) Document outlines the software's functionality, performance, and constraints, serving as a crucial reference throughout the development lifecycle.

It translates the software requirements identified in the previous phase into comprehensive specifications that effectively guide the actual development process. Design can be further divided into high-level design, which outlines the overall system architecture, providing a big-picture view of how different units interact and data flows within the system, and low-level design, which involves the detailed design of individual components, specifying how each part will be implemented and how it will operate. This stage is essential for ensuring that the architecture meets the functional and non-functional requirements of the software, such as performance, security, and scalability. Proper design is crucial as it helps prevent potential problems early in development, minimizing the risk of costly changes or rework later on. Additionally, a well-structured design ensures that the final product is robust and maintainable, facilitating easier updates and modifications in response to future requirements. : The finalization of critical elements such as the user interface, which focuses on how users will interact with the software, the application architecture that defines the structure of the system, the test plan that outlines how the software will be validated, along with the comprehensive Design Document that serves as a reference point for both developers and stakeholders throughout the development process. This detailed documentation not only aids in maintaining consistency but also provides a clear guideline for measuring progress and ensuring that the end product aligns with the initial vision and requirements.
- Development refers to the process of creating software through various methodologies and practices that facilitate effective and efficient outcomes.: Code development, interface development, version control, and staging environment.
- Testing: Unit Testing, integration testing, system testing, user acceptance testing, and load testing. Bugs are fixed in this phase.
- Deployment: Installation on production, testing production, transition to operation, and going live.
- Maintenance: Post-development support, bug checks, ongoing maintenance, and new requirements and code enhancements.
Project Methodologies
- Common methodologies include:
- Waterfall: A linear process with distinct phases. The output of one phase becomes the input of the next.
- V-shape: Emphasizes testing throughout the development process, with each test phase directly linked to a corresponding development phase.
- Agile: An iterative and incremental process where requirements and solutions evolve through collaboration with customers.
Agile Manifesto
- Values individuals and interactions over processes and tools.
- Working software over comprehensive documentation.
- Customer collaboration over contract negotiation.
- Responding to change over following a plan.
Agile Methods
-
Scrum: A framework for managing product development, with specific roles, events, and artifacts.
- Roles: Product Owner, Scrum Master, and Development Team.
- Events: Sprints (timeboxed iterations), Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective.
- Artifacts: Product Backlog, Sprint Backlog, and Increment.
- Kanban: A system for managing workflow, focused on visualizing tasks and making continuous improvements.
- Extreme Programming (XP): A methodology that emphasizes frequent releases, close collaboration, and continuous testing.
Real Life Examples
- Each example in the text shows a different SDLC phase.
Software Versions
- Track updates using semantic versioning: A major release version, a minor release, patch version, and a build version separated by a dot.
- Used to keep track of releases and bug fixes.
- Major version is used for new releases with major changes.
- Minor version is used for updates with new features or minor changes.
- Patch version is used to fix bugs in existing releases.
- Build version, or last number in the version string, is for insignificant changes.
- Examples:
- V1.0: A release, first major version.
- V3.1: An update. Third major release version, first minor release version.
- V3.1.33: A bug fix. Third major release version, first minor release version, 33rd patch version.
- V3.1.33.6: Build, bug fix, or minor change specific to a build.
Version Compatibility
- Older versions may not work well on newer versions.
- Compatibility issues are critical.
- Backward compatible means older software can work on newer versions.
