You are designing a Windows Azure SQL Database for an order fulfillment system. You create a table named
Sales.Orders with the following script.
Each order is tracked by using one of the following statuses:
Fulfilled
Shipped
Ordered
Received
You need to design the database to ensure that that you can retrieve the following information:
The current status of an order
The previous status of an order.
The date when the status changed.
The solution must minimize storage.
More than one answer choice may achieve the goal. Select the BEST answer.
A.
To the Sales.Orders table, add three columns named Status, PreviousStatus and ChangeDate. Update
rows as the order status changes.
B.
Create a new table named Sales.OrderStatus that contains three columns named OrderID, StatusDate, and
Status. Insert new rows into the table as the order status changes.
C.
Implement change data capture on the Sales.Orders table.
D.
To the Sales.Orders table, add three columns named FulfilledDate, ShippedDate, and ReceivedDate.
Update the value of each column from null to the appropriate date as the order status changes.
