# Connect Data Source Users to Select Star

Learn how to connect and align data source users with Select Star for a comprehensive view of user activities and data usage through popularity analytics.

Select Star tries to connect users between data sources automatically, so you have a single view of user activities and usage between your data warehouses and BI tools.

If you don’t have emails associated with the data source account (i.e., Snowflake or Postgres users), it is recommend that you to connect them in the Select Star UI.

## Mapping data source users to Select Star users

Select Star will automatically map data source users to Select Star users based on their emails. Assuming the same email is used in Select Star as in Looker, for example, that will be detected automatically.

For data warehouses, the usernames may not be detected automatically, so admins can map them in the **Settings** page.

From the Settings page, click on a data source. You'll see a page with all the users Select Star has identified from your data source's metadata in one column. In the other, you'll be able to choose or type a filter to bring up the matching Select Star user.

### Service Accounts

To make your popularity calculations more accurate, you'll want to mark your ETL users as Service Accounts.

Put a check ☑️ in the **Service Account** column if you'd like Select Star to recognize it is not a person that interacts with your data in a meaningful way.

Activities from Service Accounts will be weighted at much less when calculating Popularity, so that your popularity score is driven by human users, not recurring ETL jobs.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.selectstar.com/data-source-management/connect-data-source-users-to-select-star.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
