A database in MySQL is a structured collection of data that is stored electronically in a computer system. MySQL allows users to create, manage, and manipulate databases to store information in an organized way, making it easy to retrieve and manage. A database contains tables that hold related data, and is defined by schemas that dictate how data can be stored and accessed.
For example, an e-commerce site might have a database that contains tables for users, products, orders, and shipping information, allowing the application to efficiently manage all aspects of sales and customer service.
// Example of creating a database in MySQL
CREATE DATABASE ecommerce;
// Example of creating a table within the ecommerce database
USE ecommerce;
CREATE TABLE users (
id INT AUTO_INCREMENT PRIMARY KEY,
username VARCHAR(255) NOT NULL,
password VARCHAR(255) NOT NULL,
email VARCHAR(255) NOT NULL
);
