WordPress Architecture

WordPress Core

The WordPress Core is the central software that provides the foundational features and functionality of WordPress.


Themes are templates that control the visual appearance of a WordPress website.


Plugins enhance the functionality of WordPress by adding specific features or extending existing ones.


WordPress uses a database to store and retrieve website content.

Themes and Plugins Directories

WordPress maintains official directories for themes and plugins.

Application Programming Interface (API)

WordPress provides an API that allows developers to interact with WordPress from external applications or services.

Web Server

WordPress runs on a web server that handles incoming HTTP requests and serves the appropriate web pages.

Content Delivery Network (CDN)

A CDN can be integrated with WordPress to improve website performance and speed.

These components work together to power the WordPress ecosystem and provide a flexible and extensible platform for building and managing websites.

Internal Structures of WordPress

Core Tables

  • wp_postmeta: Stores metadata associated with posts and custom post types.
  • wp_terms: Stores the taxonomy terms.
  • wp_term_relationships: Associates posts with taxonomy terms.
  • wp_users: Stores user information.
  • wp_comments: Stores comments made on posts.

Post Types

  • Posts: The default post type for blog entries.
  • Pages: Used for static pages like the homepage, about page, etc.
  • Custom Post Types: Users can define their own post types to suit specific content needs.


  • Categories: Used to organize posts into broad subject areas.
  • Tags: Used for creating keyword-based tags associated with posts.

Custom Taxonomies

Users can create custom taxonomies to organize content in a hierarchical or non-hierarchical manner.


WordPress employs hooks, also known as action hooks and filter hooks, to allow developers to modify and extend the behavior of WordPress.


  • single.php: Used to display single posts.
  • page.php: Used to display individual pages.
  • archive.php: Used to display a collection of posts based on date, category, author, etc.


Permalinks determine the structure of the URLs for individual posts, pages, and other content types.
