Denormalization Strategies
Apply denormalization techniques to create flat data structures that reduce query complexity and increase speed.
What is Denormalization?
In traditional relational databases, we "normalize" data to avoid redundancy. But NoSQL databases like Firebase Realtime Database often benefit from the opposite: denormalization.
Denormalization involves intentionally adding redundant data or grouping data to optimize read performance. It's a key strategy for speed in NoSQL.
Why Firebase Needs Denormalization
Firebase Realtime Database excels at real-time updates and quick reads. However, complex queries across multiple data paths can be slow and costly.
- Flat Structures: Firebase works best with flat data structures.
- Reduced Reads: Denormalization can reduce the number of reads needed for common queries.
- Query Limitations: NoSQL databases have limited querying capabilities compared to SQL.
