30 shapes in 4 stencils of shapes (4 metric and 4 in US units, all in Visio VSS, VSX, VSSX and VSDX formats) that can be used to create Gane-Sarson and SSADM dataflow, Entity-Relationship and Entity Life History diagrams. The templates provide a blank drawing canvas and define the way connections flow on drawings.
All the symbols have connection points at suitable locations.
The Data Store and Process shapes each have shape data (or custom properties in older Visio versions) accessed from the ribbon Data -> Shape Data (in older Visio: menu Shape -> Custom Properties) to allow you to enter and show an optional ID for each shape. The Data Store and Process symbols also have a version which always prompts for the ID and Process name when the shape is dropped on the page. Dataflows may also be named by double-clicking the shape and entering the appropriate text. Dataflows may also be set to be curved, straight or angled from the dataflow right-click menu.
