The System Development Life Cycle (SDLC) is a structured process used for developing information systems. It consists of several phases, including planning, analysis, design, implementation, and maintenance. Each phase has specific tasks and deliverables, ensuring that the system meets user requirements and functions effectively. During the planning phase, project goals are defined, and feasibility is assessed. The analysis phase involves gathering requirements from stakeholders. In the design phase, system architecture is created, followed by the implementation phase, where the actual system is built. Finally, the maintenance phase ensures the system remains functional and up-to-date.
