Which of the following describes an attribute in data terms?

• A. A unique key identifier
• B. A property that defines an entity
• C. A relationship between entities
• D. A type of data model

Answer: (B)

An attribute in data terms is best described as a property that defines an entity. In data management, an entity represents an object or concept that can have data stored about it, such as a person, organization, or product. Attributes provide more detailed information about these entities by representing specific characteristics or properties. For instance, if the entity is a "Person," the attributes could include "First Name," "Last Name," "Date of Birth," and "Address." Each of these attributes adds meaningful detail that helps to describe the entity effectively. Understanding attributes as properties is fundamental in data modeling because it allows data professionals to structure data in a way that accurately reflects real-world scenarios. This concept is pivotal in designing databases and ensuring that data elements are organized to facilitate data integrity and usability.
