Related concepts

• Data productA data product is a curated dataset published for reuse, with a named owner, documentation, quality guarantees and access rules. Typical examples are a daily client exposure table or a cleaned transaction history used by several reports and models.
• Data lakeA data lake is a large store that keeps data in its raw form, structured or unstructured, until someone needs it. It is cheap and flexible, but without catalogue, ownership and quality controls it can become a "data swamp" that nobody trusts.
• Data warehouseA data warehouse is a central database that stores cleaned, structured and historical data from many source systems, organised for reporting and analysis. Data marts are smaller subject-specific extracts of it, for example for finance or risk.
