Background
Corporate Information
Fabrikam, Inc. is a retailer that sells electronics products on the Internet. The company has a headquarters site
and one satellite sales office.
You have been hired as the database administrator, and the company wants you to change the architecture of
the Fabrikam ecommerce site to optimize performance and reduce downtime while keeping capital
expenditures to a minimum. To help with the solution, Fabrikam has decided to use cloud resources as well as
on-premise servers.
Physical Locations
All of the corporate executives, product managers, and support staff are stationed at the headquarters office.
Half of the sales force works at this location.
There is also a satellite sales office. The other half of the sales force works at the satellite office in order to
have sales people closer to clients in that area. Only sales people work at the satellite location.
Problem Statement
To be successful, Fabrikam needs a website that is fast and has a high degree of system uptime. The current
system operates on a single server and the company is not happy with the single point of failure this presents.
The current nightly backups have been failing due to insufficient space on the available drives and manual drive
cleanup often needing to happen to get past the errors. Additional space will not be made available for backups
on the HQ or satellite servers. During your investigation, you discover that the sales force reports are causing
significant contention.
Configuration
Windows Logins
The network administrators have set up Windows groups to make it easier to manage security. Users may
belong to more than one group depending on their role.
The groups have been set up as shown in the following table:
Server Configuration
The IT department has configured two physical servers with Microsoft Windows Server 2012 R2 and SQL
Server 2014 Enterprise Edition and one Windows Azure Server. There are two tiers of storage available for use
by database files only a fast tier and a slower tier. Currently the data and log files are stored on the fast tier of
storage only. If a possible use case exists, management would like to utilize the slower tier storage for data
files.
The servers are configured as shown in the following table:
Database
Currently all information is stored in a single database called ProdDB, created with the following script:
The Product table is in the Production schema owned by the ProductionStaff Windows group. It is the main
table in the system so access to information in the Product table should be as fast as possible.
The columns in the Product table are defined as shown in the following table:
The SalesOrderDetail table holds the details about each sale. It is in the Sales schema owned by the SalesStaff
Windows group.
This table is constantly being updated, inserted into, and read.
The columns in the SalesOrderDetail table are defined as shown in the following table:
Database Issues
The current database does not perform well. Additionally, a recent disk problem caused the system to go down,
resulting in lost sales revenue. In reviewing the current system, you found that there are no automated
maintenance procedures. The database is severely fragmented, and everyone has read and write access.
RequirementsDatabase
The database should be configured to maximize uptime and to ensure that very little data is lost in the event of
a server failure. To help with performance, the database needs to be modified so that it can support in-memory
data, specifically for the Product table, which the CIO has indicated should be a memory-optimized table. The
auto-update statistics option is set off on this database.
Only product managers are allowed to add products or to make changes to the name, description, price, cost,
and supplier. The changes are made in an internal database and pushed to the Product table in ProdDB during
system maintenance time. Product managers and others working at the headquarters location also should be
able to generate reports that include supplier and cost information.
Customer data access
Customers access the company’s website to order products, so they must be able to read product information
such as name, description, and price from the Product table. When customers place orders, stored procedures
called by the website update product quantity-on-hand values. This means the product table is constantly
updated at random times.
Customer support data access
Customer support representatives need to be able to view and not update or change product information.
Management does not want the customer support representatives to be able to see the product cost or any
supplier information.
Sales force data access
Sales people at both the headquarters office and the satellite office must generate reports that read from the
Product and SalesOrderDetail tables. No updates or inserts are ever made by sales people. These reports are
run at random times and there can be no reporting downtime to refresh the data set except during the monthly
maintenance window. The reports that run from the satellite office are process intensive queries with large data
sets. Regardless of which office runs a sales force report, the SalesOrderDetail table should only return valid,
committed order data; any orders not yet committed should be ignored.
Historical Data
The system should keep historical information about customers who access the site so that sales people can
see how frequently customers log in and how long they stay on the site. The information should be stored in a
table called Customer Access. Supporting this requirement should have minimal impact on production website
performance.
Backups
The recovery strategy for Fabrikam needs to include the ability to do point in time restores and minimize the risk
of data loss by performing transaction log backups every 15 minutes.
Database Maintenance
The company has defined a maintenance window every month when the server can be unavailable. Any
maintenance functions that require exclusive access should be accomplished during that window.
Project milestones completed
Revoked all existing read and write access to the database, leaving the schema ownership in place.
Configured an Azure storage container secured with the storage account name MyStorageAccount with the
primary access key StorageAccountKey on the cloud file server.
SQL Server 2014 has been configured on the satellite server and is ready for use.
On each database server, the fast storage has been assigned to drive letter F:, and the slow storage has
been assigned to drive letter D:

system maintenance time. Product managers and others working at the headquarters location also should be
able to generate reports that include supplier and cost information.
Customer data access
Customers access the company’s website to order products, so they must be able to read product information
such as name, description, and price from the Product table. When customers place orders, stored procedures
called by the website update product quantity-on-hand values. This means the product table is constantly
updated at random times.
Customer support data access
Customer support representatives need to be able to view and not update or change product information.
Management does not want the customer support representatives to be able to see the product cost or any
supplier information.
Sales force data access
Sales people at both the headquarters office and the satellite office must generate reports that read from the
Product and SalesOrderDetail tables. No updates or inserts are ever made by sales people. These reports are
run at random times and there can be no reporting downtime to refresh the data set except during the monthly
maintenance window. The reports that run from the satellite office are process intensive queries with large data
sets. Regardless of which office runs a sales force report, the SalesOrderDetail table should only return valid,
committed order data; any orders not yet committed should be ignored.
Historical Data
The system should keep historical information about customers who access the site so that sales people can
see how frequently customers log in and how long they stay on the site. The information should be stored in a
table called Customer Access. Supporting this requirement should have minimal impact on production website
performance.
Backups
The recovery strategy for Fabrikam needs to include the ability to do point in time restores and minimize the risk
of data loss by performing transaction log backups every 15 minutes.
Database Maintenance
The company has defined a maintenance window every month when the server can be unavailable. Any
maintenance functions that require exclusive access should be accomplished during that window.
Project milestones completed
Revoked all existing read and write access to the database, leaving the schema ownership in place.
Configured an Azure storage container secured with the storage account name MyStorageAccount with the
primary access key StorageAccountKey on the cloud file server.
SQL Server 2014 has been configured on the satellite server and is ready for use.
On each database server, the fast storage has been assigned to drive letter F:, and the slow storage has
been assigned to drive letter D:

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 contain 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.

Background
Corporate Information
Fabrikam, Inc. is a retailer that sells electronics products on the Internet. The company has a headquarters site
and one satellite sales office.
You have been hired as the database administrator, and the company wants you to change the architecture of
the Fabrikam ecommerce site to optimize performance and reduce downtime while keeping capital
expenditures to a minimum. To help with the solution, Fabrikam has decided to use cloud resources as well as
on-premise servers.
Physical Locations
All of the corporate executives, product managers, and support staff are stationed at the headquarters office.
Half of the sales force works at this location.
There is also a satellite sales office. The other half of the sales force works at the satellite office in order to
have sales people closer to clients in that area. Only sales people work at the satellite location.
Problem Statement
To be successful, Fabrikam needs a website that is fast and has a high degree of system uptime. The current
system operates on a single server and the company is not happy with the single point of failure this presents.
The current nightly backups have been failing due to insufficient space on the available drives and manual drive
cleanup often needing to happen to get past the errors. Additional space will not be made available for backups
on the HQ or satellite servers. During your investigation, you discover that the sales force reports are causing
significant contention.
Configuration
Windows Logins
The network administrators have set up Windows groups to make it easier to manage security. Users may
belong to more than one group depending on their role.
The groups have been set up as shown in the following table:
Server Configuration
The IT department has configured two physical servers with Microsoft Windows Server 2012 R2 and SQL
Server 2014 Enterprise Edition and one Windows Azure Server. There are two tiers of storage available for use
by database files only a fast tier and a slower tier. Currently the data and log files are stored on the fast tier of
storage only. If a possible use case exists, management would like to utilize the slower tier storage for data
files.
The servers are configured as shown in the following table:
Database
Currently all information is stored in a single database called ProdDB, created with the following script:
The Product table is in the Production schema owned by the ProductionStaff Windows group. It is the main
table in the system so access to information in the Product table should be as fast as possible.
The columns in the Product table are defined as shown in the following table:
The SalesOrderDetail table holds the details about each sale. It is in the Sales schema owned by the SalesStaff
Windows group.
This table is constantly being updated, inserted into, and read.
The columns in the SalesOrderDetail table are defined as shown in the following table:
Database Issues
The current database does not perform well. Additionally, a recent disk problem caused the system to go down,
resulting in lost sales revenue. In reviewing the current system, you found that there are no automated
maintenance procedures. The database is severely fragmented, and everyone has read and write access.
RequirementsDatabase
The database should be configured to maximize uptime and to ensure that very little data is lost in the event of
a server failure. To help with performance, the database needs to be modified so that it can support in-memory
data, specifically for the Product table, which the CIO has indicated should be a memory-optimized table. The
auto-update statistics option is set off on this database.
Only product managers are allowed to add products or to make changes to the name, description, price, cost,
and supplier. The changes are made in an internal database and pushed to the Product table in ProdDB during
system maintenance time. Product managers and others working at the headquarters location also should be
