Where does data go to buy groceries? The data mart!
A data mart is a specialized and compact subset of a data warehouse that focuses on providing data to a specific group of users or for a specific business function. Unlike the vast and comprehensive nature of data warehouses, data marts are designed to cater to a particular audience, delivering valuable insights for specific needs and requirements.

Types of data marts:
- Dependent data marts: divided sections within an enterprise warehouse, the storage of all business data in one location where the data marts can extract primary data for analysis.
- Independent data marts: data is extracted from internal or external sources, processed, and then stored, does not rely on a data warehouse.
- Hybrid data marts: data from existing warehouses and other operational sources.
They offer improved performance and query response times since they are smaller and focus on a limited dataset. Data marts are also easy to maintain and manage due to their reduced scope, making them more cost-effective for businesses.
Data marts represent a valuable asset for organizations seeking efficient and tailored data solutions.
