Hi,
    I would like to know that in WEKA, although there is an interface(Open DB... i \
believe?) accessing other databases like Access or MySQL, must all the data be \
convert to .arff format and stored somewhere in the main momery before mining \
processing?  Or can WEKA access relational database table data directly while mining? \
Cuz i am wondering if the amount of data i want to mine is about GB or TB, can WEKA \
scale to that? and there is rare database using flat file to store these GB or TB \
data, mostly, they will be stored in relational database.

    Thank you for your help!
Maggie
