The cycle that software follows from requirement specification to testing and release is known as a software development life cycle model. Various SDLC models exist, each describing the different way in which software is developed.


These stages assist experts in constructing quality software that meets the united states of america whatsapp database requirements development life cycle styles that lend a hand in many kinds of development jobs , even in cases when the consumer lack a clear image of what they really demand. The "Waterfall Model" is a method to develop software or systems where development happens in stages.
