scenario is repeated in each question. Each question presents a different goal and answer choices, but the text
of the scenario is exactly the same in each question in this series.
You have a database named Sales that contains the following database tables: Customer, Order, and
Products. The Products table and the Order table are shown in the following diagram.

The customer table includes a column that stores the data for the last order that the customer placed.
You plan to create a table named Leads. The Leads table is expected to contain approximately 20,000 records.

Changes to the price of any product must be less a 25 percent increase from the current price. The shipping
department must be notified about order and shipping details when an order is entered into the database.
You need to implement the appropriate table objects.
Which object should you use for each table? To answer, drag the appropriate objects to the correct tables.
Each object may be used once, more than once, or not at all. You may need to drag the split bar between

3. Deleting records in the Product table must not be allowed if records are referenced by the ProductReview
table.
4. Changes to records in the Product table must propagate to the ProductReview table.
You also have the following databse tables: Order, ProductTypes, and SalesHistory, The transact-SQL
statements for these tables are not available.

1. Create new rows in the table without granting INSERT permissions to the table.
2. Notify the sales person who places an order whether or not the order was completed.
