Answer
Indexes can slow down write operations like INSERT and UPDATE.
While indexes speed up data retrieval, they require maintenance during data changes. Each insertion or update may need to adjust the index, adding overhead. For example, adding an index to the 'order_date' column in an 'orders' table improves query speed but may slow down order entries.
