Yahoo! Query Language thoughts – snarfed.org
Currently, YQL is not part of a cloud database. It’s strictly a hosted service for query processing. On the plus side, this means that YQL isn’t limited to a single data source. It’s not even limited to Yahoo’s own properties. YQL can operate on any third party data source, as long as it’s in one of the usual suspect formats: RSS, ATOM, JSON, XML, etc.
