Modeling Application Architecture & Information System Processes
Physical Data Flow Diagrams
- Physical Data Flows:
- Physical data flow names use one of the following general formats:
- implementation medium : data flow name
- data flow name : implementation method
- For data transmitted across a network, the implementation media should indicate the file transfer protocol to be used.
- For data transmitted between processes that are to be part of the same program, you could specify parameters and variables to be passed between the program modules.
