Difference between redo logs and undo tablespace

556809Jan 17 2007 — edited Jun 27 2008

Hello,

I'm an Oracle novice and from what I've read so far, it seems that you should be able to do rollbacks and data recovery using the redo logs. I'm having a difficulty understanding the need for the undo tablespace.

Can someone clarify the difference between the two?

Thanks,

Arthur
