What to Look for in a WordPress Database Plugin

WordPress Core Database Table Setup

Here, we will first look at how a WordPress database is set up and the way it functions.

WordPress has 11 core tables, which it utilizes to store all the information on your website. However, the users likely see more than 11 tables in their database.

This is because WordPress plugins and themes can create their own tables. So, the number of tables you see in your database also depends on which theme and plugins you install.

Here are the 11 core tables that are indigenous to WordPress by respective information that they house within them.

wp_comments – Stores all the comments.

wp_commentmeta – Stores meta information for the comments.

wp_links – Creates and stores links menu.

wp_options – Stores options set in the admin settings area.

wp_postmeta – Stores meta information for posts.

wp_posts – Stores data for posts, pages, and other custom post types.

wp_terms – Stores a list of tags and categories for all posts and links.

wp_usermeta – Stores meta-information about users

wp_users – Stores a list of users.

wp_term_relationships – Stores the relationship between a post and its category and tag and links and link categories.

wp_term_taxonomy – Stores a taxonomy label in the wp_terms table. Taxonomy refers to a category, link, or tag.

Common Issues That Slow Down Your Database

It is also essential to know why your sites must be slowing down and negatively impacting your website. Below are some things that you should look out for:

  • Poor indexing
  • Excessive use of locks or contention
  • High network latency
  • Lack of database maintenance
  • Inefficient query design
  • Inefficient database schema design
