How do denormalization techniques in database design impact system performance and data redundancy?
- Degrade system performance and increase redundancy
- Have no impact on system performance
- Improve redundancy but not system performance
- Improve system performance and reduce redundancy
Denormalization in database design involves reducing the level of normalization for performance reasons. While it can improve query performance, it may increase data redundancy and degrade system performance due to extra storage and maintenance overhead.
