The emerging data mining tools and systems lead naturally to the demand of a powerful data mining query language, on top of which many interactive and exible graphical user interfaces can be developed.

Portions of the proposed DMQL language have been implemented in our DBMiner system for interactive mining of multiple-level knowledge in relational databases.
