You are designing a data warehouse hosted on SQL Azure. The data warehouse currently includes the
dimUser and dimDistrict dimension tables and the factSales fact table. The dimUser table contains records for
each user permitted to run reports against the warehouse, and the dimDistrict table contains information about
sales districts. The system is accessed by users from certain districts, 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 districts. Some users must be permitted to see sales data from multiple districts.
What should you do?
A.
Create a userDistrict table that contains primary key columns from the dimUser and dimDistrict tables.
B.
Partition the factSales table on the district column.
C.
Add a district column to the dimUser table.
D.
For each district, create a view of the factSales table that includes a WHERE clause for the district.
