Coddex is a relational database interface for humans. Compare to phpMyAdmin and phpPgAdmin, only that feels more like a user application than an administrative interface. The goal is to make an interface that provides the full functionality and flexibility of the underlying relational database; but with a visual, discoverable presentation.
From a technical perspective, Coddex might be thought of as a web interface for SQLAlchemy, the definitive Python SQL library.
Upstream coddex source is published via the civilfritz gitweb.
I've also recently resumed pushing it up to GitHub, where I've moved the upcoming features to-do list.
