Data Warehouse
A data warehouse is a central repository that stores structured data from across a business for analysis and reporting. In a modern first-party data stack, the warehouse often serves as the owned source of truth that other tools read from and write to.
Cloud data warehouses have made it practical to centralize customer data at scale, query it flexibly, and keep it under your own control.
Paired with reverse ETL, a warehouse can act as the hub of a composable customer-data stack, feeding resolved profiles and segments out to marketing and sales tools.
