Analysis Diagrams

A data flow diagram (DFD) is a graphical representation of the flow of data through an information system, modeling its process aspects. Often they are a preliminary step used to create an overview of the system which can later be elaborated. DFDs can also be used for the visualization of data processing (structured design).

Developing Physical Data Flow Diagrams

Developing Physical Data Flow Diagrams. After you develop the logical model of the new system, you may use it to create a physical data flow diagram. The physical data flow diagram shows how the system will be constructed, and usually contains most, if not all, of the elements found in the table illustrated below.

DATA FLOW DIAGRAMS. A data flow diagram (DFD) graphically describes the flow of data within an organization. It is used to document existing systems and to plan and design new systems. There is no black-and-white approach to developing a DFD. A data flow diagram consists of four basic elements: Data sources and destinations. appear as squares.
