SDLC (Software Development Life Cycle) is a step-by-step process used to plan, build, test, deploy, and maintain software. It helps teams develop high-quality applications in an organized way.
The main SDLC phases are Planning, Requirements Analysis, Design, Development, Testing, Deployment, and Maintenance. Each phase has a specific purpose to ensure the software works correctly and meets business requirements.
In simple words, SDLC is a structured roadmap that guides a software project from the initial idea to the final product and its ongoing maintenance.
