Data Warehouse

Problem

Your production database processes customer orders all day. Analysts now run enormous queries across five years of sales. Those analytical workloads can interfere with operational traffic and need a different data shape.

Solution — Data Warehouse

Move and organize data for analytical querying.

Operational systems
        ↓
   Warehouse
        ↓
BI / Analytics

Core idea: a data warehouse separates analytical workloads from operational transaction systems.
