Abstract
We designed, implemented, and evaluated a new concept for visualizing and
searching databases utilizing direct manipulation called dynamic queries.
Dynamic queries allow users to formulate queries by adjusting graphical
widgets, such as sliders, and see the results immediately. By providing a
graphical visualization of the database and search results, users can find
trends and exceptions easily. User testing was done with eighteen
undergraduate students who performed significantly faster using a dynamic
queries interface compared to both a natural language system and paper
printouts. The interfaces were used to explore a real-estate database and
find homes meeting specific search criteria.
