Did you use any data flow diagramming programs? Did you ever use Visio? The current pricing is not too bad. I remember paying $700+ and now it looking like a full professional version is about $350 but it can be rented for as little as $30 a month. 

Below is a link to an app that a couple of friends recommended as it runs on all platform and it allows the documents to be shared and collaborated:

...and: https://www.yworks.com/products/yed

I persoanlly have been playing around with LibreOffice Draw, but I am not in the business anymore and the price is right:

I could no imagine building or maintaining any significant database application without flow charting.

Aside: I have been working on seeing if I could migrate (re-write) a MSAccess application in LibreBase... It is definitely a bit of a challenge as there are only "event driven macros" and not as I am use to "full VB programming" but the resultant application can be migrated to the web... a definite plus and challenge. The BASE uses a ODB format similar to MDB, both proprietary but it is easy to export to SQL.

Ah yes, the seminal work on the  Gane and Sarson notation for  Data Flow Diagrams.
A very widely used Systems Analysis tool in all sorts of fields, not just POS system.

I still use G&S notation DFDs  as a primary design tool :-)
