You can use a data flow diagram in Visio to document the logical flow of data through a set of processes or procedures. Visio lets you include external sources and destinations for the data, activities that transform the data, and stores or collections where the data is held.
You can design data flow models using the Data Flow Model Diagram template, which includes shapes for all the symbols used in the Gane-Sarson notation.
The Data Flow Model template uses a top-down design strategy for creating data flow diagrams. You begin by creating top-level processes. Then you decompose each process into subprocesses for more detail.
