What are the trade-offs of denormalization in databases?

Denormalization involves reducing the normalization of a database to improve read performance. However, it can lead to data redundancy and potential inconsistencies.

Can you explain how it affects data integrity?

Sure! Denormalization can compromise data integrity because it increases the chances of having duplicate data, which may not be updated consistently.

What are some scenarios where denormalization is beneficial?

Denormalization is beneficial in read-heavy applications, like reporting systems or data warehouses, where performance is prioritized over write efficiency.

Are there any best practices for denormalization?

Yes, some best practices include carefully selecting which tables to denormalize, monitoring performance impacts, and ensuring that data consistency is maintained through application logic.

How do I decide if I should denormalize my database?

Evaluate your application's read vs. write patterns, performance requirements, and the complexity of maintaining data integrity before deciding to denormalize.
