    Study Notes

    Normalization

    • Normalization is not used to improve data security.

    Objectives of Normalization

    • The main objective of normalization is to minimize data redundancy and dependency.

    Characteristics of a Well-Normalized Table

    • A well-normalized table has minimal data redundancy and dependency.

    Functional Dependency in Normalization

    • Functional dependency is used to identify the relationship between attributes in a table, helping to eliminate data redundancy and anomalies.

    Purpose of the Normalization Process

    • The normalization process aims to organize data in a database to minimize data redundancy, improve data integrity, and reduce anomalies.
