You are designing a data warehouse hosted on Windows Azure SQL Database. The data warehouse currently includes the dimUser and dimRegion dimension tables and the factSales fact table. The dimUser table contains records for each user permitted to run reports against the warehouse, and the dimRegion table contains information about sales regions.
The system is accessed by users from certain regions, as well as by area supervisors and users from the corporate headquarters.
You need to design a table structure to ensure that certain users can see sales data for only certain regions. Some users must be permitted to see sales data from multiple regions.
What should you do?
