Waterfall Model
The SDLC has 4 phases that are used when developing a library management system. Those phases are planning and selection, analysis, design, and implementation.

waterfall model is suitable for this as the requirements are clear and it is a simple model to develop.

Waterfall Model
What is SDLC?A software cycle deals with various parts and phases from planning to testing and deploying. All these activities are carried out in different ways, as per the needs. Each way is known as a Software Development Lifecycle Model (SDLC)What are the different SDLC Models ?1.Rapid application development(RAD) (including methods like SCRUM, Agile & Extreme Programming);2.The linear or waterfall model(which was the original SDLC method);3.Joint application development (JAD);4.The iterative model;5.The v-model;6.The prototyping model;7.The fountain model;8.The spiral model;9.Build and fix;10.synchronize-and-stabilize

Spiral Model
Build and fix model is the worst model. It does not involve any steps for SDLC and is highly expensive.

SDLC has both verification and validation activities where as STLC has only validation activity. Simply STLC is a part of SDLC

SDLC refers to a stage all systems naturally undergo, a methodology refers to an approach invented by humans to manage the events naturally occurring in the SDLC
