How does a data mart differ from a data warehouse in terms of data integration?

  • Data marts are smaller and more focused subsets of a data warehouse
  • Data marts have more historical data than data warehouses
  • Data warehouses are only used for reporting purposes
  • Data warehouses do not support data integration
A data mart is a smaller, more focused subset of a data warehouse that is designed for a specific business unit or department. Unlike data warehouses, data marts are not intended for enterprise-wide use, and they contain data that is tailored to the needs of a particular group.
