# Connect to MongoDB

Your administrator must create a Data Source for [MongoDB](https://www.mongodb.com/) that you can access. See [Connect to MongoDB](/cloud/admin/data-administration/external-data/config-starburst-data-sources#create-a-mongodb-data-source) in the [Admin Guide](/cloud/admin).

After your administrator has created the Data Source, you can [work with it in your project](/cloud/platform-capabilities/core-concepts/data/data-source-connectors/use-data-sources) as usual.

<Note>
  Domino data sources do not support querying nested objects. The workaround is to [`UNNEST`](https://count.co/sql-resources/bigquery-standard-sql/unnest) the object in the SQL query.

  The following is an example `UNNEST` query:

  ```python theme={null}
  res = ds.query("""
  select account_id, t1
  from sample_analytics.transactions
  cross join unnest (transactions)
  as t(t1, t2, t3, t4, t5, t6)
  """)
  ```
</Note>

## Next steps

* After connecting to your Data Source, learn how to [Use Data Sources](/cloud/platform-capabilities/core-concepts/data/data-source-connectors/use-data-sources).

* [Share this Data Source](/cloud/platform-capabilities/core-concepts/data/sharing-and-security/share-data-sources) with your collaborators.
