LP8 Assignment: Systems Design and ImplementationBinyam WorkuMT3500 - Managing Information SystemsNovember 4, 2016System Design and ImplementationSystem development life cycles involve many phases before the completion of a fully functioning information system. Before it is developed, a system must be designed, which means establishing the architecture, data, components, interfaces, and modules needed for satisfaction of specified requirements. These factors are the complete specifications used in constructing the information systems (Reynolds and Stair, 2016). The system’s architectural design is the design describing the system’s structure and behavior as well as more views. The logical design represents the system’s data flow, inputs, and outputs. The physical design is the system’s actual input and output processes. As such, more definition happens on how data is input, authenticated, processed, and displayed. Certain requirements are decided in the physical design such as input/output requirements, processing requirements, backup/recovery, and storage requirements. These requirements make up the user interface, data, and process design subtasks involved in the physical design phase. The user interface deals with addition of information by the users as well as how data is presented back to the
