  • @prakashpasupathy1612
    @prakashpasupathy1612 12 ปีที่แล้ว

    Shiv, good video and I gained better understanding on Indexes. Thanks shiv.
    1) You've said that Indexes create B-Tree, This is applicable for clustered index right for non-clustered index it won't create B-Tree right?
    2) You've said, while creating index, it creates B-Tree and which in-turn organizes the data in B-Tree fashion. so on what basis the split happens? means how split of data happen?
    Thanks,
    Prakash.

    Great videos, I appreciate the time and effort and the fact that they are free and educational. But I would like to offer some constructive criticism as it's always surreal to hear advanced technical presentations interspersed with "right?", "what do you call", etc. Also I have to ask, is the word "only" pronounced "one-ly" in some places or is that an error? Otherwise thank you for making this material available.
