GNU Ferret is a graphical data modeler based in the Entity/Relationship paradigm. It supports the automatic conversion of the data models to relational schemas, and the generation of SQL in several dialects (such as MySQL and Postgresql).


Source releases are available from the main GNU server (HTTPSHTTPFTP), and its mirrors; please use a mirror if possible.

  • <>, the main discussion list; it is used to discuss most aspects of ferret, including development and enhancement requests, as well as bug reports;
