10 Best Data Visualization Tools in 2026

BigQuery is Google's serverless data warehouse. Load data, write SQL, and get results fast regardless of whether you're querying gigabytes or petabytes. No infrastructure to manage, no clusters to tune. Pricing scales with usage—pay for queries and storage, not idle capacity. Built-in machine learning lets you train models with SQL. Streaming ingestion handles real-time data. Data teams choose BigQuery when they want analytics power without database administration. It's the warehouse that just works.

dbt transforms data in your warehouse using SQL. Write SELECT statements, and dbt handles dependencies, testing, and documentation—software engineering practices applied to analytics code. Version control for transformations. Tests ensure data quality. Documentation generates automatically from code. Data teams treat dbt as essential because it brought engineering discipline to analytics workflows that used to be undocumented SQL scripts.
