When dealing with semi-structured data in Snowflake, what advantages do native data types offer over traditional relational data types?

Question

Options

• ANative data types offer higher data integrity and consistency
• BNative data types provide flexibility in handling varied data structures
• CNative data types limit query complexity and optimization
• DNative data types enforce strict schema requirements

• A
  4% (1)
• B
  92% (23)
• D
  4% (1)

Explanation

Native data types in Snowflake - specifically VARIANT, OBJECT, and ARRAY - are designed precisely for semi-structured data (JSON, Avro, XML, etc.) where the schema can vary between records, making flexibility their defining advantage. Unlike rigid relational columns, a VARIANT column can store deeply nested, evolving structures without requiring a predefined schema, which is the core problem semi-structured data presents.

Why the distractors are wrong:

• A is backwards - native types relax schema constraints, which can reduce integrity guarantees compared to typed relational columns.
• C is wrong because Snowflake's native types actually enable complex queries via dot-notation and functions like FLATTEN, rather than limiting them.
• D contradicts the premise - enforcing strict schemas is the hallmark of traditional relational types, not native ones.

Memory tip: Think of VARIANT as a "shapeshifter" column - its whole purpose is to hold whatever shape the data arrives in. Flexibility = semi-structured. Strictness = relational.
