Data Mart
A data mart is a subset of a data warehouse, that contains information that is needed specific to the requirements of the business.
Data mart helps data/ business teams to access and analyze the data that is relevant to them, instead of going through all of the data warehouse.
What’s the difference between a data mart and a data warehouse?Data warehouses have extensive data for the entire organization, whereas data marts concentrate on a portion of that data tailored for specific groups. This specialization enables quicker and more precise data access, streamlining data retrieval and analysis by dealing with smaller, more manageable datasets.
