# Removing a data source

Remove a data source when you no longer want to process the raw data from that source in the Pentaho Data Mastering application.

You must have admin privileges to remove a data source.

Perform the following steps to remove a data source:

1. On the left navigation menu, click **Master Data**. The **Master Data** page opens.
2. In the **Resources** card, click **Data Sources**.

   The Data Sources page opens with the list of existing data sources shown in a table.
3. At the end of the data source row that you want to remove, click the more actions icon and select **Remove**.

   The Remove Data Sources confirmation box appears.
4. Click **Remove**.

   A confirmation message is shown at the top of the page and the data source record is removed from the data source table.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/pentaho-data-mastering/sourcing-data/removing-a-data-source.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
