Explain the concept of indexing in databases and its significance.
- Ensures data integrity
- Improves query performance
- Increases storage space
- Reduces data redundancy
Indexing in databases involves creating data structures to improve the speed of data retrieval operations like SELECT queries. By organizing data in a specific order, indexing reduces the time required to locate and retrieve data, thus improving query performance. However, indexing may increase storage space requirements and can lead to slight overhead during data modification operations.
