Wordpress database - what is it, how does it work and where is it located?

What is a WordPress database?

A WordPress database is a structure that stores all the information necessary for your site to function. It contains the content of posts, pages, comments, settings, as well as user information. It is a collection of tables managed by MySQL – one of the most popular relational database management systems (RDBMS).

WordPress uses SQL (Structured Query Language) to communicate with the database. It makes it possible to add, edit, delete and retrieve information dynamically. This means that every change made on the site, such as publishing a new article or changing a user’s password, is saved in the database.

Why does WordPress require a database?

A database is a key part of how WordPress works because it allows you to dynamically manage your site’s content and settings. Here are some reasons why WordPress needs a database:

1. Storing content – all posts, pages, comments and more are stored in database tables.
2. Maintaining site structure – the database contains information about menus, categories, tags and other aspects of content organization.
3. User management – WordPress stores information about users, their roles, passwords and account settings.
4. Operation of plugins and themes – plugins and themes often add their own tables to the database, where their settings and data are stored.
5. Efficiency and performance – WordPress uses a database to load the site faster, avoiding static HTML files.

Without a database, a WordPress site couldn’t work, and all content would have to be saved manually in files, making it much harder to manage the site.

How does a WordPress database work?

Every WordPress site has its own database, which is created automatically when the system is installed. WordPress uses MySQL to store and manage the data. The operation of the database can be described in a few steps:

1. Storing data – when a user adds a new post, comment or changes a setting, WordPress sends an SQL query to the database to save this information.
2. Reading data – when a visitor accesses an entry, WordPress sends a query to the database, retrieves the content and displays it on the page.
3. Updating data – changing the title of an entry, editing a comment or changing a user’s password requires executing the appropriate SQL query.
4. Deleting data – if a user deletes an entry or page, WordPress sends an SQL statement deleting the records from the database table.

The database runs in the background, handling all site operations, and users and site administrators do not need to have advanced technical knowledge to manage it.

How does the WordPress database organize information?

WordPress organizes its data in relational tables. Each table stores a specific type of information. Here are the basic tables found in the WordPress database:

• wp_posts – stores posts, pages, attachments and other custom content types.
• wp_comments – stores user comments, their content and status (accepted, spam, etc.).
• wp_users – stores information about users, such as their names, email addresses and hashed passwords.
• wp_options – contains WordPress settings, plugins and basic site information.
• wp_terms – stores categories and tags used in content.
• wp_terms – stores additional data about categories and tags.
• wp_term_relationships – manages relationships between entries and categories and tags.
• wp_term_taxonomy – stores information about the types of taxonomies used on the site.
• wp_postmeta – stores metadata of entries, such as custom fields added by users or plugins.
• wp_usermeta – stores additional information about users, such as their roles or individual preferences.

Each table contains multiple columns that store specific data. For example, the wp_users table contains columns such as user ID, username, email address and password.

Where to find the WordPress database?

The WordPress database is located on the server where the site is hosted. To access the database, you can use the phpMyAdmin tool , which is available in most hosting panels (e.g. cPanel, Plesk, DirectAdmin).

How to access the database via phpMyAdmin?

1. Log in to the hosting panel – go to cPanel, Plesk or any other panel provided by the hosting.
2. Open phpMyAdmin – in the database management section you will find the phpMyAdmin icon.
3. Select the WordPress database – the database usually bears the name given during WordPress installation.
4. Manage data – in phpMyAdmin you can view, edit and export database data.

Alternative methods of accessing the database

• WP-CLI – a command-line tool that allows you to manage WordPress, including the database.
• wp-config.php file – contains information about the database name, username and password to MySQL.
• Database management plug-ins – such as WP-DBManager, which allows optimization and backup.

Summary

The WordPress database is a key component of any site based on this CMS. It stores all content, settings and user data, allowing dynamic management of the site. Thanks to the MySQL system, the data is efficiently organized and easily accessible.

In order to better understand how WordPress works, it’s a good idea to familiarize yourself with the database and learn basic operations, such as viewing tables in phpMyAdmin, optimizing the database or creating backups. Conscious database management allows you to have better control over your site and increases its security.

User questions

What database is used in WordPress?

WordPress uses MySQL as its database management system by default. MySQL is an open source relational database management system (RDBMS) that allows WordPress to store and retrieve data in an efficient way.

In some cases, WordPress can also run on MariaDB, which is a fully compatible fork of MySQL and a frequently used alternative. Advanced users can configure WordPress to work with other databases, such as PostgreSQL or SQLite, but this requires custom modifications, as WordPress natively supports MySQL/MariaDB.

How to access the WordPress database?

To access the WordPress database, log into your hosting panel (e.g. cPanel, Plesk) and open the phpMyAdmin tool. Then select your site’s database and manage its content.

How to create a searchable database in WordPress?

You can use plugins such as WP Data Access or Search & Filter to create a searchable database. Alternatively, you can use custom SQL queries and WordPress functions to filter the results.

How to secure a WordPress database?

To secure your database, change the default table prefix, use strong passwords, update WordPress and plugins regularly, and enable two-factor authentication. It’s also a good idea to limit database access to only trusted IP addresses.

How do you back up your WordPress database?

The easiest way is to use plugins such as UpdraftPlus or WPVivid. You can also manually export the database via phpMyAdmin or use the tools available in the hosting panel.

How to optimize your WordPress database?

Regularly delete unused data, such as old versions of posts and spam comments. You can also use plugins, such as WP-Optimize, to automatically clean and optimize the database for better site performance.
