Study Notes
Software Engineering
Software Development Lifecycle (SDLC)
- Definition: A structured process for developing software applications.
-
Phases:
- Planning: Identify project goals, scope, feasibility, resources, and timeline.
- Requirements Analysis: Gather and document functional and non-functional requirements from stakeholders.
- Design: Create system architecture and design specifications; include UI/UX elements.
- Implementation: Write and integrate code based on design documents; adhere to coding standards.
- Testing: Verify that the software meets requirements; includes unit, integration, system, and acceptance testing.
- Deployment: Release the software to users; involves installation, configuration, and data migration.
- Maintenance: Provide ongoing support, fix issues, make updates, and add features based on user feedback.
Agile Methodologies
-
Definition: An iterative approach to software development that promotes flexibility and customer collaboration.
-
Key Principles:
- Customer Collaboration: Involve stakeholders throughout the development process.
- Iterative Development: Break projects into small, manageable increments called sprints.
- Responding to Change: Adapt to changing requirements, even late in development.
- Continuous Improvement: Regularly reflect on and improve team processes.
-
Common Frameworks:
-
Scrum:
- Roles: Product Owner, Scrum Master, Development Team.
- Events: Sprint Planning, Daily Standup, Sprint Review, Sprint Retrospective.
- Artifacts: Product Backlog, Sprint Backlog, Increment.
-
Kanban:
- Visualizes work using a board (Kanban board).
- Focuses on continuous delivery and limiting work in progress (WIP).
-
Extreme Programming (XP):
- Emphasizes technical excellence and frequent releases.
- Practices include pair programming, test-driven development (TDD), and continuous integration.
-
-
Benefits of Agile:
- Increased flexibility and adaptability.
- Faster delivery of functional software.
- Enhanced customer satisfaction through regular feedback cycles.
- Improved collaboration and communication within teams.
Software Development Lifecycle (SDLC)
- Structured Process: A systematic approach to developing software applications.
-
Key Phases:
- Planning: Establishes project objectives, determines feasibility, allocates resources, and sets timelines.
- Requirements Analysis: Involves collecting and recording requirements, both functional and non-functional, from stakeholders.
- Design: Develops the system architecture and design specifications, focusing on user interface and user experience.
- Implementation: Coding phase where software is developed and integrated following design documents while adhering to coding standards.
- Testing: Ensures the software fulfills requirements through various testing methods such as unit, integration, system, and acceptance testing.
- Deployment: Involves the release of the software for user access, encompassing installation, configuration, and data migration.
- Maintenance: Ongoing support to rectify issues, implement updates, and enhance features based on user feedback.
Agile Methodologies
- Iterative Approach: Focuses on incremental progress in software development, encouraging flexibility and stakeholder collaboration.
-
Key Principles:
- Customer Collaboration: Engages stakeholders continuously throughout the development lifecycle.
- Iterative Development: Divides projects into small, manageable components known as sprints for easier management and delivery.
- Responding to Change: Allows for adjustments to requirements, accommodating late-stage changes during development.
- Continuous Improvement: Encourages teams to regularly assess and refine their processes for better efficiency.
-
Common Frameworks:
-
Scrum:
- Defined roles include Product Owner, Scrum Master, and Development Team.
- Key events include Sprint Planning, Daily Standup, Sprint Review, and Sprint Retrospective.
- Artifacts encompass the Product Backlog, Sprint Backlog, and Increment.
-
Kanban:
- Utilizes a visual board to track work progress.
- Aims for ongoing delivery and limiting work in progress (WIP) to enhance efficiency.
-
Extreme Programming (XP):
- Focuses on high technical standards and rapid release cycles.
- Incorporates practices like pair programming, test-driven development (TDD), and continuous integration.
-
Scrum:
-
Benefits of Agile:
- Enhances flexibility and adaptability to change.
- Accelerates the delivery of functional software to clients.
- Increases customer satisfaction through frequent feedback iterations.
- Fosters improved collaboration and communication among team members.
