Every time somebody gets your WordPress website, the information is pulled from the database using a string of SQL queries.
All information employed by your website is stored in tables from the database. It’s possible to think about a table for a storage container for a single kind of information, which means that your information is stored organized by maintaining several types of information in various tables.
These are the core WordPress tables:
Wp_postmeta: Meta information for every article. Meta information is added into the table if you add a custom field for the articles so for instance, you can incorporate what music you’re listening to at the time of composing the article.
Wp_comments: All of your comments on pages and posts such as author, date, and email, etc..
Wp_commentmeta: Meta information for remarks.
Wp_users: Usernames, passwords (encrypted), and other consumer information.
Wp_usermeta: Meta information for consumers.
Wp_options: Overall WordPress configurations.
Wp_links: Employed for blogroll connections, not actually utilized on many WordPress sites now.
Wp_terms: Tags and categories for articles.
Wp_termmeta: Meta information for tags and groups.
Wp_term_relationships: Hyperlinks articles with tags and groups.
Every table in the database has various fields. For example wp_users has:
- User_pass
