SOFTWARE ENGINEERING

Detailed explanation-1: -The Waterfall model is the earliest SDLC approach that was used for software development. The waterfall Model illustrates the software development process in a linear sequential flow. This means that any phase in the development process begins only if the previous phase is complete.

Detailed explanation-2: -Waterfall is a classical SDLC methodology that follows logical progression of linear and sequential phases within the project lifecycle process. Some of the key principles in Waterfall include: Sequential structure. Typically includes phases such as Requirements, Design, Implementation, Verification, and Maintenance.

Detailed explanation-3: -A traditional SDLC is a linear sequential model. This model assumes that the system will be delivered near the end of its development life cycle. Another SDLC model employs prototyping, which is often used to develop an understanding of system requirements without developing a final operational system.

Detailed explanation-4: -The Waterfall methodology-also known as the Waterfall model-is a sequential development process that flows like a waterfall through all phases of a project (analysis, design, development, and testing, for example), with each phase completely wrapping up before the next phase begins.
