Case Study 2: Contoso, Ltd (Question 47 – Question 51)
Contoso, Ltd., is the developer of an enterprise resource planning (ERP) application. Contoso is designing a new version of the ERP application. The previous version of the ERP application used SQL Server 2008 R2. The new version will use SQL Server 2012. The ERP application relies on an import process to load supplier data. The import process updates thousands of rows simultaneously, requires exclusive access to the database, and runs daily. You receive several support calls reporting unexpected behavior in the ERP application. After analyzing the calls, you conclude that users made changes directly to the tables in the database.
The current database schema contains a table named OrderDetails. The OrderDetails table contains information about the items sold for each purchase order. OrderDetails stores the product ID, quantities, and discounts applied to each product in a purchase order. The product price is stored in a table named Products.
The Products table was defined by using the SQL_Latin1_General_CP1_CI_AS collation. A column named ProductName was created by using the varchar data type. The database contains a table named Orders. Orders contains all of the purchase orders from the last 12 months. Purchase orders that are older than 12 months are stored in a table named OrdersOld.
The previous version of the ERP application relied on table-level security.
The current version of the database contains stored procedures that change two tables. The following shows the relevant portions of the two stored procedures:
The current version of the ERP application requires that several SQL Server logins be set up to function correctly. Most customers set up the ERP application in multiple locations and must create logins multiple times.
Index Fragmentation Issues
Customers discover that clustered indexes often are fragmented. To resolve this issue, the customers defragment the indexes more frequently. All of the tables affected by fragmentation have the following columns that are used as the clustered index key:
Customers who have large amounts of historical purchase order data report that backup time is unacceptable.
Users report that when they search product names, the search results exclude product names that contain accents, unless the search string includes the accent.
Missing Data Issues
Customers report that when they make a price change in the Products table, they cannot retrieve the price that the item was sold for in previous orders.
Query Performance Issues
Customers report that query performance degrades very quickly. Additionally, the customers report that users cannot run queries when SQL Server runs maintenance tasks.
During the monthly import process, database administrators receive many supports call from users who report that they cannot access the supplier data. The database administrators want to reduce the amount of time required to import the data.
File Storage Requirements
The ERP database stores scanned documents that are larger than 2 MB. These files must only be accessed through the ERP application. File access must have the best possible read and write performance.
Data Recovery Requirements
If the import process fails, the database must be returned to its prior state immediately.
You must provide users with the ability to execute functions within the ERP application, without having direct access to the underlying tables.
You must reduce the likelihood of deadlocks occurring when Sales.Prod and Sales.Proc2 execute.
You need to recommend a solution that addresses the index fragmentation and index width issue. What should you include in the recommendation? (Each correct answer presents part of the solution. Choose all that apply.)
A. Change the data type of the modifiedBy column to tinyint.
B. Change the data type of the lastModified column to smalldatetime.
C. Remove the id column from the clustered index.
D. Remove the modifiedBy column from the clustered index.
E. Change the data type of the id column to bigint.
F. Remove the lastModified column from the clustered index.
You need to recommend changes to the ERP application to resolve the search issue. The solution must minimize the impact on other queries generated from the ERP application. What should you recommend changing?
A. the index on the ProductName column
B. the data type of the ProductName column
C. the collation of the ProductName column
D. the collation of the Products table
You need to recommend a solution that addresses the concurrency requirement. What should you recommend?
A. Call the stored procedures in a Distributed Transaction Coordinator (DTC) transaction.
B. Modify the stored procedures to update tables in the same order for all of the stored procedures.
C. Make calls to Sales.Proc1 and Sales.Proc2 synchronously.
D. Break each stored procedure into two separate procedures, one that changes Sales.Table1 and one
that changes Sales.Table2.
You need to recommend a solution that addresses the backup issue. The solution must minimize the amount of development effort. What should you include in the recommendation?
B. Table partitioning
C. Indexed views
