提到：

偶在想，对于传统操作数据库可不可以进行连续的挖掘呢？
例如，对于不断更新的操作数据库每隔一段时间（例如一天
或者一星期）进行一次完整的挖掘，在此基础不断的上进行
增量挖掘。可以形成挖掘出的知识库，根据这些知识库联合
操作数据库，进行连续的决策支持，并对挖掘出的知识的正
确性进行评价，对已经实施的决策进行评估。并实施对决策
的修改。
且不论软硬件代价，这个思想是否可行呢？还是早有类似的
理论？
望有识者告知！

i have read some paper on 增量式更新数据挖掘,
i think u'd better find some to read...

对的，
增量挖掘是一定会使用到的。
但是，普通的增量挖掘可以针对操作数据库么？

the aim that this method is presented is to resolve changeable database,
i think it should operate on database... 
in details, i think u may read some on it, then u can know well...

There are quite some work on incremental data mining, for example, keeping
the negative boundary information in the last session. And I see no major
difficult to apply it to the operational database, am I right?

However, if the update is constrained, better algorithms might be found. But 
I guess this idea is easy to think of and must have been done by someone, :-)

BTW, do you mean "operational DB"?

提到：

yeah,i mean "operational DB".
but when we talk about OLAP,we say it's hard to operate on operational DB.
why can we say DM on operational DB is OK?
and i think my idea is straightforward,but hard to archieve.
what i want to know is not incremental DM to get some certain knowledge,but kn
owledge base.
and  using the knowledge base to verify knowledge and decision-making.
if you have some papers about this topic,can you send it by mail?
my mail is [e-mail].
whole paper or link are both OK. 
thank you for attention to my topic.
