---|---|---|---|
(2016 / Size of non-leaf row) - 2 |
= |
No. of non-leaf index rows per page |
(2016 / 40) - 2 = 48 |
If the number of leaf pages from step 8 is greater than 1, repeat the following division step, using the quotient as the next dividend, until the quotient equals 1, which means that you have reached the root level of the index:

No. of index pages at next level |
Example |
|
---|---|
160715 / 48 = 3349 |
Index pages, level 1 |
3349 / 48 = 70 |
Index pages, level 2 |
70 / 48 = 2 |
Index pages, level 3 |
2 / 48 = 1 |
Index page, level 4 (root level) |
