Entity-Relationship-Diagramm-Erzeuger

A simple tool to generate Entity-Relationship-Diagrams based on text input or directly from a PostgreSQL database. The format of the text schema is inspired and based on "erd" by Andrew Gallant.

Make sure you have Graphviz installed and available in your $PATH. Install the gem with gem install erde or add it to your Gemfile.
