Innovations and breakthroughs in tools for data manipulation have become invaluable tools for decision making in today’s dynamic global economy. At the center of these innovations in tools for data manipulation is visual query interface. The good old text-based interface, although still useful in many ways as posited in the article, has obvious limitations that have impacted critical decision making over the years. Thus the need for a better way of manipulating the high volume of data generated in today’s dynamic business environment could not be over emphasized. The visual query interface provides the capabilities and functionalities needed for data manipulation and decision making in today’s high volume, high speed global economy.  

This is a good example of a paper that is reader oriented. The paper is well written, and well laid out with rich examples and illustrations. I enjoyed reading the paper. It is interesting to note that while most of the authors’ research findings are obvious, some are surprisingly intriguing. Conceptually, decision accuracy should be higher with visual querying whether task complexity is high or low. However according to the authors’ research findings; decision accuracy is actually higher with text-based querying than visual querying when task complexity is low.
