Different shaped symbols are used....

 

There may be some variations on these symbols.
The symbols are linked with directed lines (lines with arrows) showing the flow of data through the system.

An example of a system flowchart is shown below...

 

Transactions are input, validated and sorted and then used to update a master file.

Note the arrows show the flow of data through the system. The dotted line shows that the Updated master file is then used as input for the next Update process.
