Learn what a data warehouse is, its role in the modern data stack, and how it differs from traditional databases.
A data warehouse is a system optimized for analytics on large volumes of structured data. Unlike transactional databases (OLTP) designed for fast inserts and updates, data warehouses (OLAP) are designed for fast queries across millions of rows – perfect for reporting, dashboards, and BI.
This video covers the specific features that make cloud data warehouses like Snowflake, BigQuery and Redshift the foundation of the modern data stack, including columnar storage, separation of storage and compute, and elastic scaling.
