Hi there

Thanks for posting in the Community!

While we're not aware of how Quickbooks uses data flow diagrams we're happy to provide more information on this specific type of diagrams.

A data flow diagram (DFD) maps out the flow of information for any process or system. It uses defined symbols like rectangles circles and arrows plus short text labels to show data inputs outputs storage points and the routes between each destination. 

Data flowcharts can range from simple even hand-drawn process overviews to in-depth multi-level DFDs that dig progressively deeper into how the data is handled. They can be used to analyze an existing system or model a new one. 

If you would like to see examples of data flow diagrams we would recommend browsing our Lucidchart template library and type "data flow" in the search engine to retrieve templates which meet your needs.

Let us know if you have any questions!
