Drakon can describe data too. From the Drakon website: What is ERIL? ERIL is a graphics language for representing data model. It is based on entity-relationship and class diagrams. Thus the name, Entity-Relationship and Inheritance Language. ERIL is a counterpart for DRAKON. The DRAKON language describes algorithms and behaviour. It is an improved version of flowcharts. DRAKON introduces some rules that make flowcharts more human-eye-friendly. http://drakon-editor.sourceforge.net/eril.html http://drakon-editor.sourceforge.net/eril.html
