Teradata Vantage Certified Associate — Question 6

What contains no user-defined information?

Answer options

• A. Entity
• B. Relation
• C. Tuple
• D. Cardinality

Correct answer: D

Explanation

The correct answer is D, as cardinality refers to the number of elements in a set or the number of tuples in a relation, and it does not include any user-defined data. In contrast, Entity, Relation, and Tuple all contain user-defined information as they are constructs that represent data in a database.
