Denormalization is combining related tables to reduce complexity and improve query performance.
It introduces controlled redundancy for faster reporting.
In one project, we merged order and customer tables for a sales dashboard.

It can increase storage and risk of inconsistent data if not managed.
As a BA, I balance denormalization with data accuracy needs.
It helps optimize reporting for end-user performance.
Denormalization is often used in data warehouses and BI systems.
