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.

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.
