I am a bit confused here. I want to know which one is used by oracle- Btree or B+ tree?
Is there any link from here I cann get some example of how data are stored in index and accessed.

I went through the Oracle concept guide but i could not understand the concept well.

Is there any link from which I can understand the index concept? Is there any pictorial demonstration
which helps to undersatnd.

Many thanks for the help!
