Data Mart: Should Marketing Get Its Own Data Slice?

Data Mart

A data mart is a subject-specific subset of a data warehouse, curated for one team or domain, such as marketing, finance, or support.

Instead of querying raw shared tables, the team works with a prepared slice containing only relevant data, already cleaned and modeled for its use cases.

Marts differ from the enterprise-wide warehouse itself, which holds everything for everyone. For marketing teams, a mart typically holds campaign, web, and CRM data shaped for attribution and pipeline reporting.

The choice affects cost, access control, performance, and who owns the definitions inside it.

A practical example

Marketing gets a mart refreshed nightly with campaign spend, form submissions, and CRM opportunities, so analysts query one clean schema instead of joining six raw sources.

What to evaluate before investing

Ask whether the vendor supports multiple marts with separate access controls and cost tracking per team.
Check how marts stay in sync with warehouse sources and what happens when upstream definitions change.
Confirm who can modify the mart's models and whether marketing can iterate without filing data-team tickets.

Limitations and tradeoffs

A dedicated mart adds a layer to maintain; if its scope overlaps poorly with other teams' needs, you risk duplicated logic and divergent metric definitions.
