Ask questions across a lot of data
A retailer might put sales records from its shops and website into BigQuery, then ask, “Which products sold most last month?” Analysts use SQL queries to ask questions like this. BigQuery stores the records in tables grouped into datasets and runs the calculations on Google’s servers.
BigQuery is one Google Cloud service used to build a data warehouse: an organised collection of data for analysis.
Good reports need good data
If sales records are missing, repeated, or defined differently across systems, a report can be misleading. Teams still need to check the data and the pipelines that bring it in, and decide who can access it.
