It's Qlik's associative difference that makes all the difference...
Qlik offers an entirely different technology for exploring your data: The Qlik Associative Engine. Designed specifically for interactive, free-form exploration and analysis, the Associative Engine fully combines large numbers of data sources and indexes them to understand the associations – without leaving any data behind. It offers powerful on-the-fly calculation and aggregation that instantly updates analytics and highlights relationships in the data, exposing both associated and unrelated values after each click.
