I have a question for anyone who has used a data mining tool. My understanding is that most data mining tools do not access your database directly, but require you to unload the data and put it into some specific flat file formats before the data mining tool can search your data. Is this true? This sounds very time-consuming and inconvenient. I am concerned that the tool won't get used very much because of the effort involved. Does anybody know of a data mining tool that can directly read database tables? If so, is there any standard data model involved? Here are my theories for why data mining tools don't read database tables directly:

Data warehouse schemas are not standard. Some are simple star-schemas, but others aren't.
In-memory tables may perform associative look-up faster than database queries.

Your ideas are appreciated.
