SDLC (Software Development Life Cycle) is a framework that defines the processes involved in software development. There are several models available in SDLC, including:
- Waterfall Model: A linear sequential approach that follows a sequence of phases, where each phase must be completed before moving on to the next one.
- Agile Model: An iterative and incremental approach to software development that emphasizes collaboration, flexibility, and customer satisfaction.
- Spiral Model: A risk-driven model that combines the iterative nature of Agile with the systematic, linear approach of Waterfall.
- V-Model: A variation of the Waterfall model that emphasizes testing and verification at each stage of the development cycle.
- Prototype Model: A model that involves creating an early, limited version of the software to gather feedback and refine requirements before full-scale development.
- Incremental Model: A model that involves building and delivering the software in small, incremental chunks, with each increment building on the previous one.
- RAD Model: A rapid application development model that emphasizes quick prototyping and iterative development.
- DevOps Model: A model that emphasizes collaboration between software development and operations teams to increase efficiency and reduce development cycles.
These models vary in their approach, emphasis, and scope, and each one is suited for different types of software development projects.
