The advantages of indexes are as follows:

- Their use in queries usually results in much better performance.
- They make it possible to quickly retrieve (fetch) data.
- They can be used for sorting. A post-fetch-sort operation can be eliminated.
- Unique indexes guarantee uniquely identifiable records in the database.
