The Data Warehouse
Captions available
The idea
A data warehouse centralizes an enterprise's data into a single repository — processed data with predetermined structure and schema, optimized for gathering business insights and supporting decisions.
In practice
A retailer's every region reporting into one queryable place is the idea operating.
Where people slip
Schema decided first; data arrives already shaped.
