Teradata Vantage Certified Associate — Question 15

What is a dimensional view?

Answer options

• A. A virtual star or snowflake schema layered over detail data.
• B. A virtual view that is layered over a metadata table.
• C. A fallback schema view that is layered over detail data.
• D. A view that provides the dimensions of the data in the table.

Correct answer: A

Explanation

The correct answer, A, accurately describes a dimensional view as it involves a virtual star or snowflake schema that organizes and layers detail data for analysis. Options B and C are incorrect because they refer to a metadata table and fallback schema, respectively, which do not capture the essence of a dimensional view. Option D is misleading as it suggests a simpler view that merely states dimensions without the structural context of star or snowflake schemas.
