The First Step to Achieve First Normal Form (1NF): A Guide by KPDI Analytics

Data Modelling & Cardinality
Written By Madhu Nannuri

Bringing data into First Normal Form (1NF) is the crucial first step in relational database design. At KPDI Analytics, we ensure each cell contains atomic values—no lists or repeating groups—to create a consistent, accessible database structure. For instance, storing multiple phone numbers in individual rows for the same contact meets 1NF standards, making data easier to query and maintain. This foundational step enables scalable, well-organised databases that support reliable insights.
