Customer Question

My name is ***** ***** and I'm trying to find out: You were given a DFD with no information. With only the information provided in the DFD, would it be possible to build a flow chart and why?
JA: Thanks. Can you give me any more details about your issue?
Customer: This is all of the information I have
JA: OK got it. Last thing — Programmers generally expect a deposit of about $18 to help with your type of question (you only pay if satisfied). Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.

I would say no - a DFD is a high-level description of how data "flows" through a system.

A flow chart describes the flow of control, usually (but not necessarily) at a much lower level, showing the actions taken by the code based on the data being processed. Loosely speaking, the DFD says "what" happens, and a flow chart shows "how" it happens.

Does that help?
