Q: What does the term 'denormalization' refer to in database design?
Solution: Denormalization refers to the process of increasing redundancy in a database to improve performance, often at the cost of data integrity.
Steps: 6
Step 1: Understand what a database is. A database is a collection of data that is organized in a way that makes it easy to access and manage.
Step 2: Learn about normalization. Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity.
Step 3: Know what redundancy means. Redundancy is when the same piece of data is stored in multiple places.
Step 4: Understand denormalization. Denormalization is the opposite of normalization. It involves intentionally adding redundancy to a database.
Step 5: Recognize the purpose of denormalization. The main goal of denormalization is to improve the performance of the database, making it faster to retrieve data.
Step 6: Acknowledge the trade-off. While denormalization can improve performance, it can also lead to issues with data integrity, meaning the data might not always be accurate or consistent.
