The wp_postmeta table stores additional metadata for posts or custom post types. This metadata can include custom fields, SEO settings, or other settings that aren’t part of the main post content. For example, if you’re using a plugin like Yoast SEO or any other custom plugin, the settings related to SEO will be saved in the wp_postmeta table.
This table is crucial for developers who build custom themes and plugins, as it allows them to associate extra information with posts and pages.

It also holds other important options, including WordPress-specific configurations and third-party plugin settings. This table is often accessed when modifying global settings through the WordPress admin panel.

The wp_terms table is used for storing tags and categories in WordPress. This table handles the basic categorization of your content, whether it’s posts, pages, or custom content types.

7. wp_term_taxonomy: Defining Relationships
In tandem with the wp_terms table, the wp_term_taxonomy table stores the relationships between terms (categories, tags, or custom taxonomies) and their respective content types.
For example, it distinguishes whether a term is a category, a tag, or a custom taxonomy like “Genres” for a movie site. This table is crucial for managing complex taxonomies and relationships in WordPress.

The wp_links table, although not frequently used in modern WordPress installations, stores information about the links added to a site’s blogroll. A blogroll is a collection of links to other websites that you want to feature.
While WordPress has moved away from using blogrolls as a standard feature, this table may still be used by some legacy themes or plugins.
