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...

tree structured fileIn this paper we model the root node insertion activity of block split tree structured files such as the B-tree and its variants. Specially, we derive formulas for the events of inserting each entry into a B+ tree root node. The formulas also apply to B-trees and may...
AVL树得名于它的发明者 G.M. Adelson-Velsky 和 E.M. Landis,他们在 1962 年的论文 “An algorithm for the organization of information” 中发表了它。 AVL树是最早的自平衡二叉树,相比于后来出现的(自)平衡二叉树(红黑树,treap,splay树)而言,它现在应用较少,但研究AVL树对于了解后面出现的常用(自)平衡...
