    Question



    In database management, what does the term "Normal Form (NF)" refer to?

    A.

    Database schema optimization

    B.

    Data encryption method

    C.

    A set of rules to reduce redundancy

    D.

    Query execution optimization

    E.

    Correct option is C

    Normal Forms (NF) are a set of rules in database design that reduce data redundancy and dependency by organizing data into related tables.
    Important Key Points:
    1. Normalization improves data integrity and eliminates duplicate data.
    2. Common forms include 1NF, 2NF, 3NF, and BCNF (Boyce-Codd Normal Form).
    3. Normalization ensures efficient data management and retrieval.
    Knowledge Booster:
    · 1NF: Eliminates repeating groups within a table.
    · 2NF: Ensures no partial dependency of any column on the primary key.
    · 3NF: Removes transitive dependencies.
    · BCNF: Ensures every determinant is a candidate key.
