System design use cases (diagram) 1.) What is the purpose of the model? 2.) Problems it solves and solutions it creates 3.) Explination of parts and how they are applied briefly Solution Systems design is the framework of designing the architecture, components, modules, interfaces, and data for a system to meet the specifications. It can an offshoot of systems theory application to product development. It lays the model for the actual input and output processes of the system. This is laid down in terms of how data is input into a system, how it is verified/authenticated, how it is processed, and how it is displayed as In Physical design, the following requirements about the system are decided. Put another way, the physical portion of systems design can generally be broken down into three sub-tasks: .
