Database and WP tables

WordPress uses a database to store and manage its content. By default, WordPress uses the MySQL database management system, but it also supports other systems like MariaDB and PostgreSQL.

When WordPress is installed, it creates a set of tables in the database to store different types of information. Some of the important tables in WordPress are:

wp_posts: This table stores all the content on the site, including posts, pages, and custom post types.

wp_users: This table stores information about the registered users of the site.

wp_comments: This table stores all the comments made on the site.

wp_options: This table stores various site options like site title, tagline, and other settings.

wp_postmeta: This table stores additional meta information about each post, like custom fields and post revisions.

These tables are essential to the functioning of WordPress, and any changes made to them should be done with care. It is important to have a backup of the database before making any changes, as any errors can result in the loss of data.
