a. Make sure that the University Info System data design project is specified in the Folder field.
b. In the File name field, specify DELTA_SDT_CHANGES.sql.

changes.

The DDL runs on the server, and your new columns and index are created in the SAMPLE database.
Check the SQL Results view to ensure that the SQL statements ran successfully. Refresh the database in
the Data Source Explorer, then verify that the new columns and index exist. One of the new columns is
displayed in Figure 7.7.
