Understanding Data Marts from Company-Wide Data Warehouse

Question:

Which of the following data marts come from a company-wide data warehouse, except one?
  1. Compensation data mart
  2. Marketing data mart
  3. Financial data mart
  4. Tax data mart

Answer:

The tax data mart does not come from a company-wide data warehouse. The compensation, marketing, and financial data marts come from a company-wide data warehouse.

Explanation:

The compensation data mart, marketing data mart, and financial data mart all come from a company-wide data warehouse. These data marts are subsets of the larger data warehouse that cater to specific areas or departments within the organization. They are designed to provide focused and detailed information relevant to their respective areas.

The tax data mart, on the other hand, is an exception as it does not originate from the company-wide data warehouse. This could be due to the sensitive nature of tax-related data and the need to keep it separate or secure in a dedicated data mart.

It is important for organizations to carefully plan and design their data marts to ensure they meet the specific needs of different departments while maintaining data integrity and security.
