ERW (Entities and Relationships on the Web) is an innovative system for handling complex databases using a Web browser. It uses the most recent standards endorsed by the W3C to offer to the user a sophisticated environment, similar to a dedicated client. Moreover, the user interface is generated in a completely automatic way starting from a conceptual description of the database by means of an XML-based description language for entity-relationship schemata. From the same description, you can also automatically obtain diagrams and documentation. ERW can be used for content management, in particular when the data is structured along complex relations.
