Gerwin is a tool that aids you in creating data models and then (perhaps) implementing it on a relational database.
You can draw your data model via an entity-relation diagram, generate the tables from it (another graphical diagram) and then generate the SQL or GerwinML that mirror such relational tables. Currently several SQL dialects are supported (for most popular free software database systems) and the GerwinML generation makes to support more targets very easy (writing a XSL for the translation from the XML to some SQL dialect, for example).
