Explain the concept of denormalization and discuss situations in which it might be appropriate to denormalize a database schema. What are the trade-offs associated with denormalization?

Expert Solution
Step 1: Introduction

Database denormalization is a database design technique that involves intentionally introducing redundancy into a relational database by incorporating duplicate or redundant data into one or more tables. This process stands in contrast to normalization, which aims to minimize data redundancy and improve data integrity by organizing data into separate tables and establishing relationships between them through keys. Denormalization, on the other hand, can be employed strategically in specific situations to optimize query performance and simplify data retrieval.
