UID (User ID)

UID, or User ID, is a unique identifier assigned to each user in the Drupal content management system (CMS). It is used to identify and differentiate users from one another, and is assigned to each user upon registration. UIDs are stored in the database and are used to track user activity, such as content creation, comments, and other interactions with the site.

UIDs are also used to assign permissions to users. For example, a user with a UID of 1 may have access to certain content or features that a user with a UID of 2 does not. This allows administrators to control who can access certain content or features on the site.

UIDs are also used to track user activity. For example, if a user with a UID of 1 posts a comment on a blog post, the UID will be stored in the database along with the comment. This allows administrators to track user activity and see which users are most active on the site.

In summary, UIDs are unique identifiers assigned to each user in the Drupal CMS. They are used to differentiate users from one another, assign permissions, and track user activity.
