Google BigQuery is a serverless, highly scalable, and cost-effective cloud data warehouse. It enables users to query petabytes of data in seconds using an SQL-like syntax. BigQuery is a fully managed service that runs on the Google Cloud Platform and supports both standard SQL and legacy SQL queries.

For example, the following code query retrieves the total number of records in a dataset:

SELECT COUNT(*) FROM [dataset_name.table_name];

The output of this query is the total number of records in the specified dataset.
