What are the best practices for denormalization in databases?

Denormalization involves combining tables to improve read performance. Key practices include identifying frequently accessed data, minimizing joins, and ensuring data redundancy is manageable.

Can you give me an example of when to denormalize?

Sure! If you have a reporting system that frequently queries data from multiple tables, denormalizing those tables can speed up query performance.

What are the risks of denormalization?

The main risks include data inconsistency, increased storage requirements, and more complex data updates, which can lead to errors.

How do I decide if I should denormalize?

Evaluate your read vs. write performance needs. If reads are significantly more frequent and performance is critical, denormalization may be beneficial.

Are there tools to help with denormalization?

Yes, there are various database design tools and query optimization tools that can assist in identifying denormalization opportunities.
