What are some examples of denormalization in databases?

Denormalization is the process of optimizing the read performance of a database by adding redundant data. For example, in a sales database, instead of having separate tables for customers and orders, you might combine them into a single table that includes customer details with each order.

Can you give me another example?

Sure! In a product catalog, instead of having separate tables for products and categories, you could denormalize by including category names directly in the product table. This reduces the need for joins when querying product information.

What are the benefits of denormalization?

The main benefits of denormalization include improved query performance, reduced complexity in queries, and faster data retrieval, especially in read-heavy applications.

Are there any downsides to denormalization?

Yes, denormalization can lead to data redundancy, increased storage requirements, and potential data inconsistency if not managed properly.
