DMQL: A Data Mining Query Language for Relational Databases
Jiawei Han, Yongjian Fu, Wei Wang, Krzysztof Koperski, Osmar R. Zai͏̈ane · 2007
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 flexible graphical user interfaces can be developed. This motivates us to design a data mining query language, DMQL, for mining different kinds of knowledge in relational databases. Portions of the proposed DMQL language have been implemented in our DBMiner system for interactive mining of multiple-level knowledge in relational databases. 1 Introduction Data mining is a promising field with flourishing R & D activities and successful systems reported recently [17, 5]. Since the tasks and applications of data mining are broad and diverse, it is expected that various kinds of flexible, interactive user interfaces for data mining will emerge. We believe that the development of successful data mining systems may resemble that of relational systems which have been dominating the database system market for decades. Although there are many dif...
