The physical design relates to … While every system design interview is different, there are some common steps you should cover, even if the conversation might not be as sequential as your ideal thought process. The functional design (FD) phase of a development project focuses on the actions of a new or revised product, program, service, or process. Define and document the design characteristics of each system element2. After the implementation of system if the system is working improperly, then documentation helps the administrator to understand the flow of data in the system to correct the flaws and get the system working. Special instructions, such as security requirements. ENTITY − It specifies distinct real world items in an application. 2.
