SOFTWARE ENGINEERING

Detailed explanation-1: -Definition: The waterfall model is a classical model used in system development life cycle to create a system with a linear and sequential approach. It is termed as waterfall because the model develops systematically from one phase to another in a downward fashion.

Detailed explanation-2: -Classical waterfall model is a software process model. It is a sequential approach where each activity of a process represents a separate phase and arrange in linear order. Another name for this model is “Linear Sequential Model”. This model divides the software life cycle into six phases.

Detailed explanation-3: -Waterfall Model. In the waterfall model (also known as the classical life cycle model), the development of software proceeds linearly and sequentially from requirement analysis to design, coding, testing, integration, implementation, and maintenance. Thus, this model is also known as the linear sequential model.

Detailed explanation-4: -The waterfall model is a sequential design process in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of Conception, Initiation, Analysis, Design, Construction, Testing, Production/Implementation, and Maintenance.
