What is the primary purpose of a data warehouse?

The main idea is that a data warehouse is built to support business intelligence by storing structured, integrated data from multiple sources in a way that makes reporting and analysis fast and reliable. It uses cleaned, modeled data with schemas optimized for querying (often star or snowflake schemas) and is designed for historical analysis and steady, repeatable BI queries. This makes it ideal for dashboards, reports, and OLAP-style analysis across time. That’s why it isn’t primarily meant for raw data as-is (that’s more like a data lake), nor for storing multimedia assets exclusively, nor solely for archival backups. The emphasis is on structured data and optimized queries to enable efficient reporting and analytics.
