How does aggregation improve query performance in a database?
- Aggregation has no impact on query performance in a database.
- Aggregation increases query complexity, leading to improved performance.
- Aggregation reduces the volume of data processed by combining records into summary values, optimizing query performance.
- Aggregation slows down query performance as it involves additional processing.
Aggregation improves query performance by reducing the amount of data processed. Instead of working with detailed records, aggregating data allows databases to handle summary values, which is more efficient for queries. This optimization becomes crucial, especially in large databases with extensive datasets.
