How WordPress Database Works?

WordPress uses a MySQL database to store all of the website’s content, settings, and metadata. The database is where WordPress stores everything that makes up a website, including posts, pages, media files, comments, user accounts, and site settings.

Here’s how the WordPress database works:

  1. Tables: The WordPress database is made up of a series of tables that store specific types of data. For example, the wp_posts table stores all of the posts on the website, while the wp_users table stores user accounts.
  2. Queries: When a user visits a WordPress site, the website sends a query to the database to retrieve the necessary data. For example, if a user visits a blog post, the website will send a query to the wp_posts table to retrieve the content of the post.
  3. WordPress API: WordPress has an API that allows developers to interact with the database and retrieve data. Developers can use this API to write custom queries that retrieve specific information from the database.
  4. Updates: When a user creates or edits content on a WordPress site, the website sends an update query to the database to store the changes. For example, if a user creates a new blog post, the website sends an update query to the wp_posts table to add the new post.
  5. Plugins and Themes: WordPress plugins and themes can also interact with the database to add or modify content. For example, a plugin might add a new table to the database to store custom data, or a theme might modify the wp_posts table to add custom fields to posts.

Overall, the WordPress database is a critical component of the website and is responsible for storing and retrieving all of the site’s content and settings. Understanding how the database works can help developers build custom plugins and themes that integrate with the WordPress API and interact with the database.
