What is the impact of database normalization on performance?

What is the impact of database normalization on performance?

Database normalization can improve performance by reducing data redundancy and ensuring data integrity. However, it may also lead to more complex queries.

Can you explain how normalization affects query speed?

Normalization can slow down query speed initially due to the need for joins between tables. But it often leads to faster updates and inserts.

Are there any downsides to normalizing a database?

Yes, while normalization reduces redundancy, it can increase the complexity of queries and may require more joins, which can impact performance.

What are the different normal forms in database normalization?

The different normal forms include 1NF (First Normal Form), 2NF (Second Normal Form), 3NF (Third Normal Form), and BCNF (Boyce-Codd Normal Form), each addressing specific types of redundancy.

When should I consider denormalization?

Denormalization may be considered when performance is critical, especially for read-heavy applications, to reduce the number of joins.
