How the Backend of your WordPress site works

By Reuben Walker, 22 May, 2022

You probably know that websites have frontends (what the public sees) and backends (the technology that creates and serves them).

In this post, we will recommend articles, that look at the coding languages, databases, and servers of WordPress. Peruse them at your leisure to see how they make the backend of WordPress work.

WP Backend

The Coding Languages of WordPress

The coding languages that make WordPress work are:

  • HTML
  • CSS
  • PHP
  • Javascript
  • SQL

Put simply, HTML provides your site's meaning and structure. CSS provides its aesthetics. Interactivity and functionality are provided by PHP and Javascript. These are the frontend languages used in WordPress. SQL is the language that allows your visitors to interact with your site's database(s). These languages control what is seen in the browser.

The five articles linked below provide overviews and resources for additional information.

The Servers of WordPress

The servers that make WordPress work are:

  • Apache

According to TechTerms, “A server is a computer that provides data to other computers. It may serve data to systems on a local area network (LAN) or a wide area network (WAN) over the Internet. Many types of servers exist, including web servers, mail servers, and file servers. Each type runs software specific to the purpose of the server.”

The vast majority of WordPress sites use Apache and, to a lesser degree, NGINX servers. The two articles linked below provide overviews and resources for additional information.

The Databases of WordPress

The databases that make WordPress Work are:

  • MySQL
  • MariaDB

According to Oracle, "A database is an organized collection of structured information, or data, typically stored electronically in a computer system. A database is usually controlled by a database management system (DBMS). Together, the data and the DBMS, along with the applications that are associated with them, are referred to as a database system, often shortened to just database.

Data within the most common types of databases in operation today is typically modeled in rows and columns in a series of tables to make processing and data querying efficient. The data can then be easily accessed, managed, modified, updated, controlled, and organized. Most databases use structured query language (SQL) for writing and querying data."

MYSQL is the database used by the majority of WordPress sites. The two articles linked below provide overviews and resources for additional information.

Wrapping Up

Explore the articles above at your leisure to see how the coding languages, servers, and databases of WordPress work together to make your site function and provide the best experience for its users.
