1. What is a B+-tree? 2. Insertion algorithm 3. Deletion algorithm 1. What is a B+-tree?Most queries can be executed more quickly if the values are stored in order. But it's not practical to hope to store all the rows in the table one after another, in sorted order, because th...
The cost of these operations may become O(n) for a skewed Binary tree. If we make sure that height of the tree remains O(Logn) after every insertion and deletion, then we can guarantee an upper bound of O(Logn) for all these operations. The height of an AVL tree is always O(Logn...
Using the known properties and the usual transformations (for insertion and deletion) of Bt+-trees, we can summarize now the relationship between the structure and operations by the following theorem. Theorem 1: PO-B+-tree properties are preserved under PO-insert and PO-delete. ...
