Mogwai ERDesigner NG is an open-source ER diagram design tool written in Java. When you draw entities and relationships, it generates DDL scripts for various database dialects, and it can reverse-engineer an existing database into a model. It is used instead of commercial modeling tools to quickly design and document schemas on the desktop.
