Why does MongoDB use B-trees?
Overview MongoDB is a general-purpose, document-oriented distributed database. This is the official introduction to MongoDB. Different from traditional relational databases MySQL, Oracle and SQL Server, one of the most important features of MongoDB is “document-oriented”. Due to the different data storage methods, the interface provided to the outside world is no longer well-known. SQL, so […]
Java handwritten B-tree application expansion case
Java handwritten B-tree application expansion case 1. Introduction B-tree is a balanced search tree used to process large data sets, and its wide range of applications covers many fields. The following is some summary of B-tree applications: Database system: B-tree is often used in the index structure of database system, such as B+ tree. By […]
Distributed database: an in-depth explanation of B-tree index
Author: Zen and the Art of Computer Programming 1. Introduction Overview With the rapid development of Internet business and the generation and flow of massive data, traditional relational databases still have some bottlenecks in high concurrency situations. Therefore, distributed databases based on distributed computing architecture emerged as the times require. This article will start from […]

SQL Server Index Explanation Series 4 B-Tree Organization of Tables
1. Overview Speaking of B-tree organization, it refers to the index, which can provide fast access to data. Indexes organize data in a specific way to provide optimal performance for query operations. When the size of the data table becomes larger and larger, indexes become very obvious, and indexes can be used to quickly find […]
C++ implements B-Tree (B-tree)
Reference: Mr. Deng Junhui “Data Structure C++ Language Implementation” B-tree nodes are composed of multiple keys, which are represented by vectors in the data structure. Similarly, children of keys also exist in vectors, and the structure is as follows: key: key0 key1 key2 key3 key4 (store value) child: child0 child1 child2 child3 child4 child5 (save […]
