An index is used to enhance the speed of data retrieval operations on a database table at the cost of additional space and maintenance overhead. It is particularly beneficial for columns that are frequently searched, sorted, or used in join operations. By creating an index, the database can quickly locate the rows that match a query, significantly improving performance, especially in large datasets. However, indexes should be used judiciously, as they can slow down write operations like inserts, updates, and deletes.
