In the context of database performance, what role does indexing play?
- Enhancing data integrity by enforcing constraints
- Facilitating data manipulation through SQL queries
- Improving data retrieval speed by enabling faster lookup
- Minimizing data redundancy by organizing data efficiently
Indexing plays a crucial role in enhancing database performance by improving data retrieval speed. It involves creating data structures (indexes) that enable faster lookup of records based on specific columns or expressions commonly used in queries. By efficiently locating relevant data without scanning the entire dataset, indexing reduces query processing time and enhances overall system responsiveness, especially for frequently accessed data.
