Which of the following describes something in a database that refers to the unique identifier in the parent table?

Process
Attribute
Server
Input

The correct answer is: Attribute

An attribute is a characteristics or property of a data entity, which can act as a unique identifier in a database. This differs from the other options as "process" refers to a series of actions, "server" is a computer or device that provides services to other devices, and "input" is data that is entered into a computer. These options do not describe a unique identifier within a database.
