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

Note that pre-defined actions, such as *Load Table*, *Create Row*, etc. are NOT supported with this datasource.

## 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.uibakery.io/reference/data-sources/bigquery.md?ask=&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.
