A diagram that shows the data object types output by one activity and later used by another activity.
A Physical data flow diagram is a representation of the flow of data into, out of, and between procedures, subsystems or systems. The diagram is similar to the process dependency diagram.
Process dependency diagrams show the dependencies that exist for business processes and do not indicate how the dependencies may be manifested. Data flow diagrams show the flow of actual data between designed business activities and data stores, thus depicting how two activities interact.
In BAA Current Systems Procedure Analysis, a diagram should be constructed for the procedure level, possibly with other diagrams abstracted to show subsystems and systems.
