Software Development Life Cycle (SDLC)
- Consists of distinct phases: Requirements Analysis, Design, Implementation, Testing, Deployment, and Maintenance, providing a structured approach to software development.
Agile Methodology
- Focuses on iterative development that promotes flexibility and active customer collaboration.
- Common frameworks used within Agile include Scrum and Kanban, allowing for adaptability in project management.
Waterfall Model
- A linear, sequential approach where each phase must be completed before the next phase begins, ensuring clear progress tracking.
Software Development Approaches
- Rapid Application Development (RAD): Prioritizes quick development and user feedback through continuous prototyping.
- DevOps: Integrates software development and IT operations to enhance collaboration, streamline processes, and increase deployment frequency.
Software Design Principles
- Separation of Concerns: Encourages the management of different software aspects independently to reduce complexity.
- DRY (Don't Repeat Yourself): Aims to eliminate program redundancy, promoting better maintainability.
- KISS (Keep It Simple, Stupid): Advocates for simplicity in design to ease understanding and reduce errors.
Testing in Software Engineering
-
Types of Testing:
- Unit Testing: Focuses on testing individual components or functions of the software.
- Integration Testing: Assesses the interactions and data flow between combined components.
- System Testing: Evaluates the entire system's conformity to specified requirements.
- Acceptance Testing: Ensures the software meets user needs and requirements prior to deployment.
- Automation: Implementing automated tools to enhance testing efficiency and coverage.
Software Maintenance
-
Types:
- Corrective Maintenance: Involves fixing identified bugs and issues.
- Adaptive Maintenance: Modifies software to accommodate changes in operational environments.
- Perfective Maintenance: Enhances system performance or adds functionalities.
Documentation
- Vital throughout the software lifecycle to facilitate maintenance, onboarding, and knowledge transfer among team members.
Project Management Tools
- Common tools include JIRA, Trello, and GitHub Projects, which aid in tracking project progress, managing tasks, and fostering collaboration among development teams.
Ethics in Software Engineering
- Emphasizes the importance of ethical considerations in the development process, ensuring that software is safe, secure, and upholds user privacy rights.
Software Engineering Overview
- Branch of computer science focused on systematic software design, development, maintenance, testing, and evaluation.
Software Development Life Cycle (SDLC)
- Phases include Requirements Gathering, Design, Implementation, Testing, Deployment, and Maintenance.
Software Requirements
- Functional Requirements: Specify what the system should do.
