Litware, Inc
Overview
You are a database administrator for a company named Litware, Inc. Litware is a book
publishing house.
Litware has a main office and a branch office.
You are designing the database infrastructure to support a new web-based application that is
being developed. The web application will be accessed at www.litwareinc.com. Both internal
employees and external partners will use the application.
You have an existing desktop application that uses a SQL Server 2008 database named
App1_DB. App1_DB will remain in production.
Requirements
Planned Changes
You plan to deploy a SQL Server 2014 instance that will contain two databases named
Database1 and Database2. All database files will be stored in a highly available SAN.
Database1 will contain two tables named Orders and OrderDetails. Databasel will also
contain a stored procedure named usp_UpdateOrderDetails. The stored procedure is used to
update order information. The stored procedure queries the Orders table twice each time the
procedure executes. The rows returned from the first query must be returned on the second
query unchanged along with any rows added to the table between the two read operations.
Database1 will contain several queries that access data in the Database2 tables.
Database2 will contain a table named Inventory. Inventory will contain over 100 GB of data.
The Inventory table will have two indexes: a clustered index on the primary key and a
nonclustered index. The column that is used as the primary key will use the identity property.
Database2 will contain a stored procedure named usp_UpdateInventory.
Usp_UpdateInventory will manipulate a table that contains a self-join that has an unlimited
number of hierarchies.
All data in Database2 is recreated each day and does not change until the next data creation
process.
Data from Database2 will be accessed periodically by an external application named
Application1. The data from Database2 will be sent to a database named App1_Db1 as soon
as changes occur to the data in Database2.
Litware plans to use offsite storage for all SQL Server 2014 backups.
Business Requirements
You have the following requirements:
• Costs for new licenses must be minimized.
• Private information that is accessed by Application must be stored in a secure format.
• Development effort must be minimized whenever possible.
• The storage requirements for databases must be minimized.
• System administrators must be able to run real-time reports on disk usage.
• The databases must be available if the SQL Server service fails.
• Database administrators must receive a detailed report that contains allocation errors
and data corruption.
• Application developers must be denied direct access to the database tables.
Applications must be denied direct access to the tables.
• You must encrypt the backup files to meet regulatory compliance requirements. The
encryption strategy must minimize changes to the databases and to the applications.

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 2014.
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_CPl_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.
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:
Backup Issues
Customers who have large amounts of historical purchase order data report that backup time
is unacceptable.
Search Issues
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.
Import Issues
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.
Design Requirements
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.
Security Requirements
You must provide users with the ability to execute functions within the ERP application,
without having direct access to the underlying tables.
Concurrency Requirements
You must reduce the likelihood of deadlocks occurring when Sales.Proc1 and Sales.Proc2 execute.

minimize the amount of development effort.
