# Deleting a data source
<a name="delete-a-data-source"></a>

You can delete a data source if you no longer need it. Deleting a query-based database data source makes any associated datasets unusable. Deleting an Amazon S3, Salesforce, or SPICE-based database data source doesn't affect your ability to use any associated datasets. This is because the data is stored in [SPICE](spice.md). However, you can no longer refresh those datasets.
