Is there anyone doing Data Flow maps? If so, can you please help me how to get started? I’d like to do simple data flow connecting multiple applications with arrows indicating the data that flow between them, in which direction etc. I tried to read the Data Flow article but it is not very helpful as it simply just assumes that you already have all the relationships maintained and only focuses on how to visualize it.
What I am looking for is how to really start from scratch - e.g. imagine I have 2 fresh application fact sheets and I want to add them to Data Flow diagram, then draw an arrow between them and on the arrow then maintain the ‘data flow attributes’ - direction, data content, maybe the method/protocol etc. I did not find easy way how to do it directly in the diagram.
Any input / guidance welcome.
BTW it is also unclear to me what is the real difference between Free Draw and Data Flow diagram editor - they seem to look exactly the same. Again, the official articles are not very helpful as they just describe when to use which but not what is the actual difference (features, limitations...) of each of those. To me it feels that I can technically do the same in both - would be great to have ‘real comparison’ of those two somewhere.
