单选题You design a Business Intelligence （BI） solution by using SQL Server 2008. You plan to create a SQL Server 2008 Reporting Services （SSRS） solution. Developers generate random reports against a data source that contains 200 tables. Power users generate random reports against four of the 200 tables. You need to design a strategy for the SSRS solution to meet the following requirements： ·Uses minimum amount of development effort. ·Provides two sets of tables in SSRS to the developers group and the power users group. Which strategy should you use？（）A
