What is WordPress directory & Database Structure ? | Explanation of WordPress Dashboard

WordPress is a popular content management system (CMS) that uses a specific directory and database structure to manage website content and settings. The directory structure is where all the core WordPress files and additional themes and plugins are stored, while the database structure is used to store website content, user information, and settings. Below, I'll outline both the directory and database structure of a typical WordPress installation.

Directory Structure:
The directory structure of a WordPress installation usually looks like this:

Root Directory (/public_html/ or /www/): This is where you typically place the WordPress core files. It contains important files like wp-config.php and folders such as wp-admin, wp-includes, and wp-content.

wp-admin: This directory contains the core files and components related to the WordPress admin dashboard.

wp-includes: It contains important core WordPress files, such as libraries and functions.

wp-content: This is a crucial directory where user-generated content and customizations are stored. It includes:

a. plugins: This is where all the installed plugins reside. Each plugin usually has its own directory here.

b. themes: Installed themes are stored in this directory. Each theme has its own directory, and it contains template files, stylesheets, and other assets.

c. uploads: Media files like images, videos, and other uploads are stored here.

d. languages: Translations and language files for the WordPress core and themes/plugins are stored here.

wp-config.php: This file contains configuration settings for your WordPress installation, including database connection details and security keys.

.htaccess: This file is used to configure server-level settings, such as URL rewriting and security rules.

Database Structure:
WordPress uses a MySQL or MariaDB database to store its data. The database structure consists of numerous tables, each responsible for storing different types of data. Some of the most important database tables include:

wp_options: This table stores various site options and settings, including site title, URL, and active theme.

wp_posts: It stores information about posts, pages, and custom post types, including their content and metadata.

wp_postmeta: This table contains metadata associated with posts, pages, and custom post types. This data can include custom fields and other information.

wp_users: User information, including usernames, passwords (hashed), and other user-related data, is stored here.

wp_usermeta: Similar to postmeta, this table stores metadata for users, such as profile information and custom fields.

wp_comments: Comments made on posts and pages are stored in this table.

wp_terms and wp_term_taxonomy: These tables are used to store taxonomy terms (categories and tags) and their relationships.

wp_term_relationships: This table maps posts to their associated taxonomy terms.

wp_links: In older versions of WordPress, this table stored links and bookmarks.

These are just a few of the core tables in the WordPress database. The actual structure may vary depending on the installed plugins and themes, as they might introduce additional tables to store their own data.
