SDLC (Software Development Life Cycle) is a systematic process used in the field of software engineering to design, develop, test, and maintain software systems. It is a structured approach that defines the various stages and activities involved in software development, from the inception of an idea to the final deployment and maintenance of the software.
The SDLC consists of several key phases: requirements gathering and analysis, system design, coding, testing, deployment, and maintenance. Each phase has its own set of objectives and deliverables to ensure the successful development and implementation of the software.
During the requirements gathering and analysis phase, the software requirements are identified, analyzed, and documented. This phase helps in understanding the needs and expectations of the users.
The next phase, system design, involves creating detailed specifications and technical architecture for the software. This phase also includes defining the database structure, user interface, and system modules.
The coding phase involves writing the actual code according to the specified design and requirements. This phase is where the software is developed by programmers using programming languages and development tools.
After coding, the software enters the testing phase, where it undergoes various tests to identify and fix any bugs or issues. This phase includes unit testing, integration testing, system testing, and user acceptance testing.
Once the software passes the testing phase, it is ready for deployment, which involves installing and configuring the software in the target environment. Finally, the software enters the maintenance phase, where updates, bug fixes, and enhancements are made to ensure its smooth operations.
Overall, the SDLC provides a framework and guidelines that help ensure the successful and efficient development of software systems by following a structured and systematic process.
