Abstract
We designed, implemented and evaluated a new concept for direct
manipulation of databases, called dynamic queries, that allows
users to formulate queries with graphical widgets, such as sliders.
By providing a graphical visualization of the database and search
results, users can find trends and exceptions easily. Eighteen
undergraduate chemistry students performed statistically
significantly faster using a dynamic queries interface compared to
two interfaces both providing form fill-in as input method, one with
graphical visualization output and one with all-textual output. The
interfaces were used to expore the periodic table of elements and
search on their properties.
