Flowchart of a Website. The System V1 flowchart depicts how data flows in a system and how decisions are made to control events. Symbols are used to illustrate the System V1 Flowchart. They are linked together to demonstrate what happens to data and where it goes. It is important to note that system flow charts are very similar to data flow charts. Data flow diagrams do not include decisions; instead, they show the path data takes, including where it is held, processed, and output. There is an input and a work for the system to function. The process involves taking information, doing something with it, modifying it, and producing an output. The output is fed back into the input as feedback.
