In denormalization, what action is taken to reduce the number of joins in SQL queries?

In denormalization, one action taken to reduce the number of joins in SQL queries is to combine multiple tables into one. By consolidating related data from different tables into a single denormalized table, the need for joining tables in SQL queries is minimized. This approach simplifies query formulation and execution, leading to improved performance, especially for read-heavy workloads. However, it's essential to carefully design the denormalized schema to avoid excessive redundancy and maintain data consistency.
