An interface that allows '''dynamic queries''' has these properties (according to C. Williamson und B. Shneiderman [Williamson and Shneiderman, 1992]):

*the graphical visualisation of the database and searching results
*delivers results immediately when several parameters are changed
*visualizes result borders (min-max)
*allows beginners a faster entrance without having much practice, and still offers experts some mighty functions
