# Big Query

UI Bakery allows you to easily connect to Big Query data warehouse with no need for additional layers like APIs or third-party services.

## Configuration

### Prerequisites

To establish a connection between UI Bakery and Big Query, you will first need to [create a private key](https://cloud.google.com/docs/authentication/getting-started).

### Connecting the data source

Once you've obtained the key, you can proceed to connecting the data source.

1. On the **Data sources** page, click **Connect**, and select *Big Query* in the Data sources list.
2. Specify your dataset, service account credentials (your private key), and region qualifier.
3. Click **Test connection** to check whether the data source can be connected, and then click **Connect Datasource** to complete the setup.

UI Bakery will extract the database structure and store column types. This data will be used to suggest the proper [table columns and form field types](/concepts/components/work-with-components/field-types-and-types-recognition.md).

## Usage

Once you've established the connection between UI Bakery and your Big Query database, you can start interacting with its data.&#x20;

To manage data from Big Query, you can use the [SQL Query](/reference/working-with-actions/sql-query.md) action step.
