Hi Experts,
I've got some conceptual doubt in Oracle's B-Tree index. I've read few articles by Richard Foote and other blogs, but still have this confusion:
Considering the Dictionary example for Indexes here, what exactly forms the Root node? I'm not able to get a clear mental image.
Each page of dictionary forms a leaf block, is it?
Please help in understand this basic but 'critical' concept part.
Help much appreciated.
