The Essential Role of Non-Key Attributes in Database Design

Data Modelling & Cardinality
Written By Madhu Nannuri

At KPDI Analytics, understanding the role of non-key attributes is crucial for creating efficient data structures that uphold data integrity. Non-key attributes, which are columns in a table not part of the primary or unique key, hold valuable details about records without uniquely identifying them. Ensuring these attributes depend solely on the primary key, as required for Third Normal Form (3NF), helps reduce redundancy and prevent data anomalies, fostering consistency and reliability in data models.
