in this example it is having two keys, then how many children it is having, so each node can have maximum 3 children. so this is three ways search tree. 3-way ST. each node

-tree) is the most popular index structure in disk-based relational database systems, the T-tree has been widely accepted as a promising index structure for main memory databases where the entire database (or most of them) resides in the main memory. However, most work on the T-tree repo...
In order to take advantage of the internal parallelism of an SSD, it is beneficial for DBMSs to request input/output (I/O) operations on sequential logical block addresses (LBAs). However, the B -tree structure, which is a representative index scheme of current relational DBMSs, produces ...
On the other hand, a Binary tree can have at most two subtrees or child nodes. B-tree is used when data is stored in disk whereas binary tree is used when data is stored in fast memory like RAM. Another area of application for B-tree is code indexing data structure in DBMS, in ...

首先大家还是先来熟悉一下典型 B*tree 索引的结构图: 很明显,从图中我们可以看到: 1. 整个索引结构由root,branch,leafblock构成。 2. 从root block到每一个leaf block的高度都是一样的。 3. 索引条目总是是唯一的且在逻辑上是有序的。 4. 索引的扫描除了iffs(索引快速全扫描)总是单块读的形式。
This makes the proposed technique a good candidate for integration in a fuzzy DBMS when it is developed as an extension of a crisp DBMS. The efficiency of the proposal is contrasted with another indexing method for similar data and queries, G-tree, which is specifically designed to index ...
