What role does indexing play in improving database query performance?
- Ensures data integrity
- Reduces storage space
- Simplifies data backup
- Speeds up data retrieval
Indexing improves database query performance by speeding up data retrieval. It works by creating an optimized data structure that allows the database management system to locate rows more efficiently based on the indexed columns. This helps reduce the time required to execute queries, especially for large datasets, resulting in faster response times for users.
