for large chunks of data . The b-tree algorithm reduces the intermediate process that is experienced when locating records, thus speeding up the access speed. Widely used in databases and file systems . ”DefinedA B-tree can be seen as an extension of the 2-3 lookup tree, that is, he allows each node to have M-1 child nodes. Root node has at least two child nodes Each node has a M-1 key and is sorted in ascending order The values of t

Introduction When you use a system frequently, you tend to get stuck in some sort of fixed usage pattern. Sometimes, you don't get into the habit of doing things in the best way possible. Sometimes, your bad habits can even lead to confusion. One of the best ways to correct such shortcomings is to consciously adopt a good habit of resisting these bad habits. This article presents 10 UNIX command-line habits that are worth taking--a good habit to help

Chapter 1 method (1) (2) and chapter 10 Method 1. What is the role of the method? Make the program shorter, clearer, and easier for program maintenance.
