WDQSs enable users to formulate queries (in other words, a dynamic interface) within the bounds of the functionalities available on the specific WDQS. Accessibility to the WDQS is on the web through a standard web browser. WDQSs produce numeric tabulations to user queries and also generate various statistics. (Friedman and Parrish, 2008)
