A purpose-built subset of the data warehouse prepared for one team's questions. The marketing mart holds customer, order, and campaign tables shaped for marketing's use, without the risk tables and logistics feeds the rest of the warehouse carries. Faster queries, simpler models, less blast radius when something upstream changes.
Also known as
marketing mart; marketing schema
How Asteroad uses it. The practical answer to "how fresh is the data marketing reports on." If your dashboards query "the marketing schema," you are already using a mart; the question worth asking your data team is how often it refreshes and who owns the definitions.
