What is Data Warehouse?
A structured repository optimized for analytical queries and business intelligence reporting.
A data warehouse is a centralized, structured repository designed specifically for analytical queries and business intelligence. Unlike operational databases optimized for transactions, data warehouses are optimized for read-heavy analytical workloads. They use schema-on-write, meaning data is cleaned, transformed, and structured before loading. This ensures high data quality and fast query performance for reporting and dashboards.
