Quizplus · Accepted Answer

A data flow diagram (DFD) is a documentation tool used to depict the flow of data between different processes in a system. It is used to illustrate how data enters the system, moves through various processes, and exits the system. This makes it an ideal tool for documenting the sources and uses of data in an organization and how they are processed by the system. A document flowchart, system flowchart, or program flowchart may be useful for other aspects of documenting the accounting information system, but a data flow diagram is the best choice for documenting the data sources and flow in this particular case.
