Data mart
A smaller collection of organised data prepared for one team or reporting need
What's it for?
Gives one team a smaller, ready-to-use set of data focused on its own reporting needs.
For example…
Managers use a smaller people dataset for workforce reports
Finance gets a data mart containing approved revenue, cost and budget data rather than querying the organisation's entire warehouse.
Think of it like…
Corner shop stocked for one neighbourhood, not the full supermarket warehouse
