The WordPress database stores all the necessary site data. Not only basic information such as user names and passwords, but also messages, pages and comments, even the website subject and WordPress configuration parameters. Today we will consider what a database is, why and how you should manage a WordPress database. Buckle up and enjoy the ride.

Why WordPress needs a database

A database is a structured set of organized data. In IT, Database Management Systems (DMS) is defined as software that interacts with the user, processes the data, and extracts and stores the data. This is almost the same when you store images or videos on your computer’s hard drive or in a business card folder if you prefer to manage an old school. Having a personal database to access this data is very useful.

There are several ways to use and access the database. WordPress uses MySQL for its database management system. MySQL is open source software and it is responsible for managing WordPress database components such as user data, user meta, publications, comments and so on.

WordPress uses PHP, using an SQL query in PHP markup, as the instruction language for CRUD (Create, Read, Update, and Delete – create, read, update, and delete) data from a MySQL database. The database is an integral part of WordPress. It is the basis, which stores all basic information. The database also ensures uninterrupted operation of your page, fully optimizes it and helps to back up your data regularly.

What is a Database Host?

Your WordPress database is hosted on a database host, which then places it on the MySQL server. Think of the database host as a real home, which you can find by knowing a specific address (host name). You can get something from the “room” section (database name). Of course, you will need permission to do so, so you need to enter a username and password before you can enter the house.

What is a database table?

Your data is stored in a database as tables. Each table consists of unique data and is displayed in rows. And the rows also contain other parts of information or parameters. By default, WordPress automatically creates these tables when you first set up your website.

WordPress version 4.4 will make the following basic database tables:

  • wp commentmeta – each comment has unique information called metadata, this data will be available in this section.
  • wp comments – all comments in WordPress will be available in this table.
  • wp links – this section contains information related to the links entered in the Links function in WordPress.
  • wp options – this section contains data that WordPress uses to store various settings and configuration options.
  • wp postmeta – each post contains unique information called metadata, this data will be available in this section.
  • wp posts – in WordPress, “posts” are articles that you write to fill in your blog.
  • wp termmeta – each term has unique information called metadata, this data will be available in this section.
  • wp terms – categories for messages and links, and tags for messages are stored here.
  • wp term relationships – messages are linked to categories and tags from the wp_terms table, and this link is maintained here.
  • wp term taxonomy – this table describes the taxonomy (category, link or tag) for entries in the wp_terms table.
  • wp usermeta – each user has unique information called metadata, this data will be available in this section.
  • wp users – this is where the user list is maintained.

By default, you cannot remove the main WordPress tables. But they will be added to your content.

What is SQL query?

SQL is an acronym for structured query language; it is a programming language used for database management. An SQL query issued for CRUD data on a database server is called a query. WordPress uses MySQL queries to store and retrieve data and generate them on web pages.

Querying can be convenient especially if you want to optimize your web page. For example, to remove spam comments that will inflate your database and slow down your web page. A query can delete them quite quickly by running the following command:

How do I manage my WordPress database?

Manage your WordPress database, or rather the MySQL server, with phpMyAdmin. It is an open source web application with an easy to use user interface.

Or even better, we have already created a unique direct link to access phpMyAdmin. Just don’t forget to specify your MySQL server username and password. Once you have clicked either the direct link or the phpMyAdmin button, it will direct you to the phpMyAdmin interface. However, you should keep in mind that every time you make a change to WordPress, these tables can be folded and added together. This is why you have to deal with it carefully.


Databases and WordPress are similar to two sides of the same coin; they work side by side to ensure that your web page works as well as possible and that all its data is well managed. Let’s take stock. We looked at the benefits of having a database to store and retrieve your data. We will also learn how to use query to simplify our database management work, and finally, we know how to perform basic WordPress database management.
