For Example, Consider the following Insertions:
Insert: 3, 12
Insert: 7, 24
Insert: 10, 48
Insert: 24, 60
Insert: 14, 72
The index file should look as follow: -1 2 -1 -1 -1 -1 -1 -1 -1 -1 -1 0 3 12 7 24 10 48 14 72 24 60 -1 3 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 4 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 5 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 6 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 7 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 8 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 9 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1
After the previous insertions, Node 1 is a leaf node and all the references in it are pointing to records on data file.
Consider the following Insertion:
The index file should look as follow: -1 4 -1 -1 -1 -1 -1 -1 -1 -1 -1 1 10 2 24 3 -1 -1 -1 -1 -1 -1 0 3 12 7 24 10 48 -1 -1 -1 -1 0 14 72 19 84 24 60 -1 -1 -1 -1 -1 5 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 6 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 7 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 8 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 9 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1
After the previous insertions, Node 1 is a non-leaf node and all the references in it are pointing to other nodes on the index file.
