Study Notes
Software Development Process Models
- Code-and-fix model: An early approach with only coding and fixing bugs; led to poorly structured code and expensive fixes. Highlighted the need for design and requirements phases.
- Prototype model: Involves quick design, prototype creation, customer evaluation, requirements refinement, implementation, testing, and maintenance. Iterative process focusing on early customer feedback.
- Spiral model: An iterative model incorporating risk analysis at each iteration. (Specific details from the referenced document are absent.)
- Incremental development: Begins with initial specification and an initial version. Subsequent iterations build upon previous versions until the final version is achieved.
- Test-driven development: A model where tests are written before the code.
Agile Software Development Manifesto
- Prioritizes individuals and interactions over processes and tools.
- Values working software over comprehensive documentation.
- Emphasizes customer collaboration over contract negotiation.
- Favors responding to change over following a plan.
Software Development Activities
- Architectural design: High-level design of the system.
- Component design: Design of individual components.
- Persistence design: Design of data storage and retrieval.
- Interface design: Design of user interfaces and interactions with other systems.
- Component testing: Testing individual components.
- System testing: Testing the entire system.
- Customer testing: Testing by the end-user.
- Deployment: Moving tested code into the production environment.
- Documentation: Essential for future maintenance and enhancement, especially for external interfaces.
- Software training and support: Crucial for successful software adoption.
Building vs. Growing Software
- The "building" metaphor likens software development to construction, implying detailed planning upfront.
- "Growing" software starts with a minimal, functional system and adds features iteratively.
DevOps
- Why DevOps? Addresses the misalignment of goals between developers and operators.
- What is DevOps? A set of practices aimed at improving collaboration between development and operations teams.
- DevOps Practices: (Specific practices are not detailed in provided text)
- DevOps Consequences: (Specific consequences are not detailed in provided text)
