Case Study: 2 Contoso, Ltd Overview
Application Overview
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. Tables
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. Stored Procedures
The current version of the database contains stored procedures that change two tables. The following shows the relevant portions of the two stored procedures:
Customer Problems Installation Issues
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:

Currently, all of the database administrators have the same level of permissions on all of the servers and all of the databases. The Customers database contains two tables named Customers and Classifications. The following graphic shows the relevant portions of the tables:

The following table shows the current data in the Classifications table:
The Inventory database is used mainly for reports. The database is recreated every day. A full backup of
the database currently takes three hours to complete. Stored Procedures
A stored procedure named sp1 generates millions of rows of data for multiple reports. Sp1 combines data from five different tables from the Sales and Customers databases in a table named Table1. After Table1 is created, the reporting process reads data from a table in the Products database and searches for information in Table1 based on input from the Products table. After the process is complete, Table1 is deleted. A stored procedure named sp2 is used to generate a product list. Sp2 takes several minutes to run due to locks on the tables the procedure accesses. A stored procedure named sp3 is used to update prices. Sp3 is composed of several UPDATE statements called in sequence from within a transaction. Currently, if one of the UPDATE statements fails, the stored procedure continues to execute. A stored procedure named sp4 calls stored procedures in the Sales, Customers, and Inventory databases. The nested stored procedures read tables from the Sales, Customers, and Inventory databases. Sp4 uses an EXECUTE AS clause. A stored procedure named sp5 changes data in multiple databases. Security checks are performed each time sp5 accesses a database. You suspect that the security checks are slowing down the performance of sp5. All stored procedures accessed by user applications call nested stored procedures. The nested stored procedures are never called directly. Design Requirements Data Recovery You must be able to recover data from the Inventory database if a storage failure occurs. You have a Recovery Point Objective (RPO) of one hour. You must be able to recover data from the Dev database if data is lost accidentally. You have a Recovery Point Objective (RPO) of one day. Classification Changes You plan to change the way customers are classified. The new classifications will have four levels based on the number of orders. Classifications may be removed or added in the future. Management requests that historical data be maintained for the previous classifications. Security

General Overview
A. Datum Corporation has offices in Miami and Montreal. The network contains a single Active Directory forest named adatum.com. The offices connect to each other by using a WAN link that has 5-ms latency. A. Datum standardizes its database platform by using SQL Server 2012 Enterprise edition. Databases Each office contains databases named Sales, Inventory, Customers, Products, Personnel, and Dev. Servers and databases are managed by a team of database administrators. Currently, all of the database administrators have the same level of permissions on all of the servers and all of the databases. The Customers database contains two tables named Customers and Classifications. The following graphic shows the relevant portions of the tables:

The following table shows the current data in the Classifications table:
The Inventory database is updated frequently. The database is often used for reporting. A full backup of
the database currently takes three hours to complete. Stored Procedures
A stored procedure named sp1 generates millions of rows of data for multiple reports. Sp1 combines data from five different tables from the Sales and Customers databases in a table named Table1. After Table1 is created, the reporting process reads data from Table1 sequentially several times. After the process is complete, Table1 is deleted. A stored procedure named sp2 is used to generate a product list. The product list contains the names of products grouped by category. Sp2 takes several minutes to run due to locks on the tables the procedure accesses. The locks are caused by sp1 and sp3.
A stored procedure named sp3 is used to update prices. Sp3 is composed of several UPDATE statements called in sequence from within a transaction. Currently, if one of the UPDATE statements fails, the stored procedure fails. A stored procedure named sp4 calls stored procedures in the Sales, Customers, and Inventory databases. The nested stored procedures read tables from the Sales, Customers, and Inventory databases. Sp4 uses an EXECUTE AS clause. All nested stored procedures handle errors by using structured exception handling. A stored procedure named sp5 calls several stored procedures in the same database. Security checks are performed each time sp5 calls a stored procedure. You suspect that the security checks are slowing down the performance of sp5. All stored procedures accessed by user applications call nested stored procedures. The nested stored procedures are never called directly. Design Requirements Data Recovery You must be able to recover data from the Inventory database if a storage failure occurs. You have a Recovery Time Objective (RTO) of 5 minutes.
