Projects / ERW


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.


Recent releases

  •  22 Jul 2005 11:30

    Release Notes: This release candidate moves ERW to PHP 5. Due to the massive usage of references, it was impossible to eliminate call-time referencing without using reference argument default values, which means that this release (and subsequent releases) will not work on PHP 4. Developers and system administrator are invited to test that their PHP 5 installations are compatible with upcoming releases. Most dependencies on specific PHP 5 non-default configuration settings should have been removed.

      Release Notes: This release preserves the original file names in filesets, and provides them both as virtual attributes and as names when downloading a file. This is the last release that will work with PHP 4. The next release will require PHP 5.
