QUESTION 16
Hotspot Question
You are developing an app that allows users to query historical company financial data. You are reviewing email messages from the various stakeholders for a project. The message from the security officer is shown in the Security Officer Email exhibit below.
TO: Database developer
From: Security Officer
Subject: SQL object requirements
We need to simplify the security settings for the SQL objects. Having a assign permissions at every object in SQL is tedious and leads to a problem. Documentation is also more difficult when we have to assign permissions at multiple levels. We need to assign the required permissions at one object, even though that object may be obtaining from other objects.
The message from the sales manager is shown in the Sales Manager Email exhibit below.
TO: Database developer
From: Sales Manager
Subject: Needed SQL objects
When creating objects for our use, they need to be flexible. We will be changing the base infrastructure frequently. We need components in SQL that will provide backward compatibility to our front end applications as the environments change so that do not need to modify the front end applications. We need objects that can provide a filtered set of the data. The data may be coming from multiple tables and we need an object that can provide access to all of the data through a single object reference. This is an example of the types of data we need to be able to have queries against without having to change the front end applications.

The message from the web developer is shown in the Web Developer Email exhibit below.
TO: Database developer
From: Web Developer
Subject: SQL Object component
Whatever you will be configuring to provide access to data in SQL, it needs to connect using the items referenced in this interface. We have been using this for a long time, and we cannot change this from end easily. Whatever objects are going to be used in SQL they must work using object types this interface references.

You need to create one or more objects that meet the needs of the security officer, the sales manager and the web developer. For each of the following statements, select Yes if the statement is true. Otherwise, select No.

QUESTION 1
You have a database that contains the following tables: BlogCategory, BlogEntry, ProductReview, Product, and SalesPerson. The tables were created using the following Transact SQL statements:

You must modify the ProductReview Table to meet the following requirements:
1. The table must reference the ProductID column in the Product table.
2. Existing records in the ProductReview table must not be validated with the Product table.
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 database tables: Order, ProductTypes, and SalesHistory. The Transact-SQL statements for these tables are not available. You must modify the Orders table to meet the following requirements:
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.
You must add the following constraints to the SalesHistory table:
– a constraint on the SaleID column that allows the field to be used as a record identifier.
– a constant that uses the ProductID column to reference the Product column of the ProductTypes table.
– a constraint on the CategoryID column that allows one row with a null value in the column.
– a constraint that limits the Sale Price column to values greater than four Finance department users must be able to retrieve data from the SalesHistory table for sales persons where the value of the SalesYTD column is above a certain threshold.
You plan to create a memory-optimized table named SalesOrder. The table must meet the following requirements:
– The table must hold 10 million unique sales orders.
– The table must use checkpoints to minimize 1/0 operations and must not use transaction logging.
– Data loss is acceptable.
Performance for queries against the SalesOrder table that use Where clauses with exact equality operations must be optimized. You need to modify the design of the Orders table. What should you create?

A.    a stored procedure with the RETURN statement
B.    a FOR UPDATE trigger
C.    an AFTER UPDATE trigger
D.    a user defined function
