B Tree Index Files by Huy Nguyen
... • Binary tree only have 2 children max. • For large files binary tree will be too high because of the limit of children and not enough keys per records. • Btrees disk size can have many children depending on the disk block. • Btrees are more realistic for indexing files because they easily maintain ...

... In a cycle there is a B every t positions … But these positions can be in arbitrary order Which i’s have a B, and how do we store it? Keep a vector of all positions 0 indicates no B 1 indicates a B Rank gives the position of B[“i”] in actual B array So: π(i) and π -1(i) in O(1) time & (1+ε)n lg n bi ...

... Disadvantages of BST The shape of the tree depends on the order of insertions, and it can be degenerated. When inserting or searching for an element, the key of each visited node has to be compared with the key of the element to be inserted/found. Keys may be long and the run time may increase ...
