Can u give me some articles which can shed light on this theme?
【 在 fervvac (高远) 的大作中提到: 】
: I think one difference might be that once one can leverage the existing data
: cube for the mining process. Prof. Jiawei Han has quite a lot of publication
: on this aspect. Note that his DM group attempted to integarte DM with DW for
: a long time and it seems they are re-focusing on this topic now.
: Another thing to mention is that most mining on top of the "relational" data
: is actually not so appropriate. They are mostly transactional data. It is 
: of course possible to convert transactional dat into relational data, but the
: value 0 and * cannot be distinguished (in original dm algorithms).
: 【 在 helloboy (hello) 的大作中提到: 】
: : 好像dW经常要涉及表的连接，在dm处理的时候复杂很多。
: : 请问有无这方面的文章？
