| An interface that allows '''dynamic queries''' has these properties (according to C. Williamson und B. Shneiderman [Williamson and Shneiderman, 1992]):
| |
| *Graphical representation of the request
| |
| *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
