I'm doing a PhD in data mining and I need more than 1600 columns. I got an error message saying that I can not use more than 1600 columns.
It is happening because I have to change categorical values to binary creating new columns. Do you know if oracle can handle it?

Hint: you can have practically unlimited rows in your n:m table :-)
