Course Introduction：This public welfare live broadcast uses Vue scaffolding to complete the single-page display of China's epidemic and global epidemic data~ The project structure is carried out using the current trend of completely separating the front and back ends. The way to display China's epidemic data is to make a China epidemic map, and the way to display global epidemic data is to make a column chart. The technical hot spots involved are as follows: 1. echarts map configuration, complex column chart configuration; 2. axios cross-domain request cache data interface; 3. tp redis caches third-party interface data and other contents;

Course Introduction：Title: Real-time data synchronization and replication using PHP and SQLite Introduction: In today's information age, real-time synchronization and replication of data are becoming more and more important. Whether it is data synchronization within an enterprise or data replication between multiple systems, an efficient and reliable method is required to achieve it. This article will introduce how to use PHP and SQLite to achieve real-time data synchronization and replication, and provide corresponding code examples. 1. Introducing SQLite and PHP extensions First, we need to ensure that SQLite has been installed in the system

Course Introduction：MySQL and PostgreSQL: Real-time Data Synchronization and Replication Technology Abstract: In today's world of data-driven applications, real-time data synchronization and replication technology are becoming increasingly important. This technology can help us maintain data consistency across multiple databases and provide data backup and fault recovery capabilities. In this article, we will focus on real-time data synchronization and replication technology in two popular open source database systems, MySQL and PostgreSQL, and give corresponding code examples. Introduction: Real-time data

Course Introduction：MySQL is a commonly used relational database management system. In practical applications, we often encounter scenarios that require data replication. Data replication can be divided into two forms: synchronous replication and asynchronous replication. Synchronous replication means that the data must be copied to the slave database immediately after the master database writes the data, while asynchronous replication means that the data can be delayed for a certain period of time after the master database writes the data before copying. This article will focus on how to implement asynchronous replication and delayed replication of data in MySQL. First, in order to implement asynchronous replication and delayed replication, I
