converting the logical design of a system to an identification of specifications for each component of the system.
System design is the evaluation of alternative solutions and the specification of a detailed computer-based solution
Describes how the processing will be performed; for example, whether data is input by a person or read by a bar code reader, whether a file is electronic or print. Tools to represent the physical design include a system flow charts and structure charts.
Specifications for the hardware and software for automated procedures. Activities performed include developing designs for the databases, inputs, outputs, and programs. 14.26
The third major stage in the design process, in which the project team determines how to specifically implement the logical design.
Describes how an information system will be physically implemented in order to meet its logical requirements. This involves specifying the technical (hardware and software) components that will enable the logical design specifications to be implemented. Tools to represent the physical design include system flow charts and structure charts.
