Waterfall Model The waterfall model represents is a methods of research that used in study, requirements, analysis, design phase, development, testing and implementation. The developers decided to use the System Development Life Cycle (SDLC) to ensure the success of the system and to easily meet the needs of the client. Requirement Analysis is a plan of basic project approach. In this stage, the developers planned to ask some questions about the problem of the store. Designing Stage is an outline of the system.

In this stage, developers tested the system if there are any errors. Lastly, is the Implementation phase, the developers will implement the system to the store.
