The Data Mart
Captions available
The idea
A data mart is a scaled-down warehouse serving a homogeneous small group — focused content, better query performance — dependent when fed from the central warehouse, independent when drawing sources directly.
In practice
A single department's numbers, close at hand, without the enterprise's whole weight.
Where people slip
Dependent or independent is a supply-chain decision.
