Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Third Normal Form (3NF)

Third Normal Form (3NF) is the standard for OLTP databases to reduce redundancy and avoid update, insert, and delete anomalies.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Denormalized form

    Why it's wrong here

    Denormalization is for OLAP/read-heavy workloads, not for OLTP with high write volumes.

  • Second Normal Form (2NF)

    Why it's wrong here

    2NF eliminates partial dependencies but not transitive dependencies.

  • Third Normal Form (3NF)

    Why this is correct

    3NF eliminates transitive dependencies and is the standard for OLTP.

  • First Normal Form (1NF)

    Why it's wrong here

    1NF only eliminates repeating groups, not all anomalies.
