• wp_links: used to manage blogrolls
• wp_options: contains most of Wordpress settings such as site url, admin email, default category, posts per page, etc. This table is also used by numerous plugins to store plugins settings.
• wp_postmeta: contains meta information about posts, pages, and custom post types. Examples of meta information would be which template to use to display a page, custom fields, and so on. Some plugins also store plugin data in this table.
