.. currentmodule:: google.cloud.bigquery

The main concepts with this API are:

• :class:`~google.cloud.bigquery.client.Client` manages connections to the BigQuery API. Use the client methods to run jobs (such as a :class:`~google.cloud.bigquery.job.QueryJob` via :meth:`~google.cloud.bigquery.client.Client.query`) and manage resources.
• :class:`~google.cloud.bigquery.dataset.Dataset` represents a collection of tables.
• :class:`~google.cloud.bigquery.table.Table` represents a single "relation".
