Scenario: A retail chain wants to analyze sales data from each of its store locations separately to identify regional trends and preferences. Would you recommend implementing a Data Warehouse or multiple Data Marts, and what factors would you consider in making this decision?
- Both Data Warehouse and Multiple Data Marts
- Data Warehouse
- Multiple Data Marts
- Neither Data Warehouse nor Multiple Data Marts
For the retail chain analyzing store-specific data, implementing multiple Data Marts is recommended. Data Marts are subsets of a Data Warehouse, focusing on specific business areas. This approach allows for tailored analysis of individual store data while maintaining the benefits of centralized data management. It provides a balance between centralized control and local flexibility.
