You design a Business Intelligence （BI） solution by using SQL Server 2008. The solution includes a SQL Server 2008 Analysis Services （SSAS） database. The database contains a data mining structure that uses a SQL Server 2008 table as a data source. A table named OrderDetails contains detailed information on product sales. The OrderDetails table includes a column named Markup. You build a data mining model by using the Microsoft Decision Trees algorithm. You classify Markup as discretized content. The algorithm produces a large number of branches for Markup and results in low confidence ratings on predictable columns. You need to verify whether the Markup values include inaccurate data. What should you do？ （）A、 Modify the content type of Markup as Continuous.B、 Create a data mining dimension in the SSAS database from OrderDetails.C、 Create a data profile by using SQL Server 2008 Integration Services （SSIS）.D、 Create a cube in SSAS. Use OrderDetails as a measure group. Recreate the data mining structure and mining model from the cube data.
