B-Tree Index

B-Tree Index. B-Tree indexes are used to avoid large sorting operations. For example, a SQL query requiring 10,000 rows to be presented in sorted order will often use a B-Tree index to avoid the very large sort required to deliver the data to the end user. . B-Tree Example.

B-Tree

B-Tree. ADT Implementation. A multi-way (or m-way) search tree of order m is a tree in which Each node has at-most m subtrees, where the subtrees may be empty . Each node consists of at least 1 and at most m-1 distinct keys The keys in each node are sorted.

B-Tree

B-Tree. Multiway search tree. A tree was defined as either an empty structure or a structure whose children are disjoint tree t 1 ,t 2 ,…t k . Each node of this kind of tree can have more than two children. This tree called a multiway tree of order m, or an m-way tree.

B-tree

B-tree. Why B-Trees. When the data is too big, we will have to use disk storage instead of putting all the data in main memory In such case, we have to take into account the fact that disk access takes much longer time than many other instructions. Disk Access Time.

B-Tree Operations

B-Tree Operations. Multi way search trees(of order m). A generalization of Binary Search Trees. Each node has at most m children. If k ≤ m is the number of children, then the node has exactly k-1 keys. The tree is ordered. B-tree of order 5.

B + TREE

B + TREE. INTRODUCTION. A B+ tree is a balanced tree in which every path from the root of the tree to a leaf is of the same length, and each non leaf node of the tree has between [n/2] and [n] children, where n is fixed for a particular tree.

B+-Tree Index

B+-Tree Index. Chapter 10. Modified by Donghui Zhang Nov 9, 2005. Motivation. Suppose every disk page holds 133 records. You are given 133 4 = 0.3 billion records. They occupy 133 3 = 2.3 million disk pages. You can utilize a small memory buffer of 134 pages.
