Suggested Answer: Explanation
Box 1: DATABASE [OnlineSales]
Before you can use change tracking, you must enable change tracking at the database level. The following example shows how to enable change tracking by using ALTER DATABASE.
ALTER DATABASE AdventureWorks2012

SET CHANGE_TRACKING = ON -
(CHANGE_RETENTION = 2 DAYS, AUTO_CLEANUP = ON)

Box 2: CHANGE_TRACKING = ON -

ALTER SET CHANGE_RETENTION -
Box 3: ALTER TABLE [dbo].[Customers]
Change tracking must be enabled for each table that you want tracked. When change tracking is enabled, change tracking information is maintained for all rows in the table that are affected by a DML operation.
The following example shows how to enable change tracking for a table by using ALTER TABLE.

ALTER TABLE Person.Contact -

ENABLE CHANGE_TRACKING -
WITH (TRACK_COLUMNS_UPDATED = ON)

Box 4: ENABLE CHANGE_TRACKING -
