Abstract: Through Integrating Data Mining technology with Data Visualization technology as well as on-line analysis processing technology, the E-Commerce Data Mining and Visualization Model (EDVM)--a model of data visualization analysis system based on data mining technology--is built, which can be applied in E-Commerce Web's environment. Its primary function is realized by technology, so the results of data mining can be updated dynamically and exported visually. At the end of this paper, the effectiveness of this model is also demonstrated by analyzing the experimental results.
