Microsoft Azure Data Fundamentals — Question 258

What is a characteristic of non-relational data?

Answer options

• A. no indexes
• B. self-describing entities
• C. a well-defined schema
• D. no unique key values

Correct answer: B

Explanation

The correct answer, B, indicates that non-relational data often has self-describing entities, allowing for flexible and dynamic data structures. In contrast, option A is incorrect because some non-relational databases can use indexes, option C is wrong as non-relational data typically does not have a rigid schema, and option D is misleading since non-relational databases can have unique key values, but they are not mandatory.
