A WordPress database is a system for managing and organizing information. You can think of a database as a digital “filing cabinet” of information.
Some databases contain data on customers, while others store product information. Database administrators manage the database, perform upgrades, create backups, and add and delete permissions.
WordPress stores all of your site’s posts, pages, media, and other content in a database. It retrieves that information from the database and displays it when a visitor requests it by typing or clicking a URL.
