From the developer:
Helma is a server-side Javascript environment and web application framework for fast and efficient scripting and serving of your websites and Internet applications. Helma pioneered the simple and codeless mapping of application objects to database tables. In addition, an embedded object-oriented database performs automatic data persistence of unmapped objects.
