For beginners: WordPress database management using phpMyAdmin

WordPress is built upon PHP as a scripting language based on MySQL database as the brain for the website for the management. Sometimes, you need to add some more features for WordPress database, so you have to know more about it and how to use it and which tool you want to make its handling easier. This blog will be focused on using phpMyAdmin.

What’s in your WordPress database?

WordPress database like any other database in the programming world. It uses MySQL programming to handle it. Actually, WordPress database is much more important for your website than your installation of WordPress. Because all the information about your website is stored in the database and all the WordPress is interface to handle this data. All you content is also stored in the database.

After each install, a number of standard tables will be created in your WordPress database 11 to be exact. Over time, plugins will add to this number with their own tables, however, the core tables for every fresh WordPress install are these:

  • wp_commentmeta: for the meta data of comments on your site.
  • wp_comments: where all comments are stored.
  • wp_links: deprecated but holding information entered in WordPress’s Link featured.
  • wp_options : everything input under Administration > Settings is stored in this table.
  • wp_postmeta: the meta data of your posts.
  • wp_posts: data for posts, pages and navigation items goes here.
  • wp_terms: mainly holds information for taxonomies such as categories and tags.
  • wp_term_relationships: this saves the relationships with posts and taxonomies.
  • wp_term_taxonomy: describes taxonomies with the wp_terms table.
  • wp_usermeta: unsurprisingly, the user meta data.
  • wp_users: all users go here.

WordPress contains all the raw data about your website, styling, media files, and everything else that makes your website presentable to browsers and users.

How WordPress uses the database?

During installation, WordPress will use the information provided by you and insert data by default into the database tables. After installation, WordPress will start running queries to the database and dynamically generate the HTML pages for the new website. This makes WordPress the most user friendly platform in web development as users don’t need to create new.html files each time to create a page.

What is phpMyAdmin?

phpMyAdmin is one of the most popular administration tool for databases. A lot of hosting providers use it to enable their customers to organize their databases. It also ships with popular development platforms such as WampServer, XAMPP, and MAMP.
