Software project development is crucial in the computer world. The Software Development Life Cycle (SDLC) aims to reduce errors and enhance final results. The SDLC provides a structured approach to creating software, involving various steps and processes. Different types of SDLC models, like the waterfall and prototype models, are used in software development. The study compares five SDLC models, including spiral and iterative structures, to understand their advantages and disadvantages.
