Case Study: 2
Contoso, Ltd
Background
You are the business intelligence (BI) solutions architect for Contoso Ltd, a multinational
sales company with offices in London, Madrid, Paris, Brisbane, Tokyo, and New York.
Contoso sells office consumable products such as pens, printer ink, and paper.
You produce solutions by using SQL Server 2012 Business Intelligence Edition and
Microsoft SharePoint Server 2010 Enterprise Edition with SP1.
Technical Background
Contoso’s products are categorized by using four levels while some use only two or three
levels. Products are categorized as shown in the following table.
Contoso sells products through mobile sales staff, direct marketing, and its website. Sales
personnel are located in various regions around the world, and each region has a sales
manager who is paid a quarterly bonus based on the total sales in the region during the
quarter. Regions are categorized as shown in the following table.
SQL Server Analysis Services (SSAS) is used to host a multidimensional database. The
database contains a single cube named Sales and three database dimensions named Products,
Regions, and Date. A single measure named Sales Total has been defined in the cube. The
data source for the database is a SQL Server data warehouse.
The Products dimension contains a single user-defined hierarchy named Products. To prevent
the display of empty members when users browse the Products dimension, the Extract,
Transform, and Load (ETL) process populates all missing values as shown in the following diagram.
The structure of the Products hierarchy is shown in the following diagram.
The Regions dimension contains a single user-defined hierarchy named Sales Regions. The
dimension is based on a single dimension table in the data warehouse and the attribute
relationships have not been modified since the dimension was created by using the
Dimension wizard. The structure of the Sales Regions hierarchy is shown in the following diagram.
The Date dimension contains a single user-defined hierarchy named Calendar. The structure
of the Calendar hierarchyis shown in the following diagram.
A role named UserRegions has been created in the SSAS database that will be used to filter
members in the Regions dimension based on the authenticated user.
Administrative staff from around the world will produce sales reports with Microsoft Excel
2010 based on the Sales cube.
Developers will produce reports with SQL Server Reporting Services (SSRS) based on the
Sales cube and the reports will be delivered to users through report subscriptions and a web
browser-All users log on to an Active Directory Domain Services (AD DS) domain named
contoso.com.
All client computers and servers are joined to the contoso.com domain.
Business Requirements
The BI system must meet the following reporting requirements:
• Display all sales figures in euro currency, regardless of the client’s reporting location
• Include a new measure named AD Sales that calculates average daily sales for a
selected month
• Support near real-time reporting while maintaining good performance for
multidimensional queries
• Support reports that show currency exchange rates
• Deliver executive reports that are parameterized and rendered from report snapshots
In addition, cube objects must use terms familiar to users from around the world. For
example, in the SalesRegions hierarchy, users from Great Britain must see the State level
presented as County when browsing the Sales cube.
The Sales cube must support a new measure group named Sales Planning. The measure group
must consist of a single measure named Sales Plan that enables the management team to use
Excel 2010 to enter sales plans for future monitoring.
The BI system must meet the following technical requirements:
Architecture requirements
o The system must use separate servers for each of the following components:
SQL Server Database Engine
SQL Server Integration Services
SQL Server Analysis Services in multidimensional mode SharePoint Server with
the Reporting Services Add-in
o All servers must be installed using U.S. regional settings.
o The system must source currency exchange rate data from a database hosted in
Microsoft Azure SQL Database.
Security requirements
o When possible, the system must use Windows authentication for all database
connections.
o The system must prevent users from querying data from outside of their region.
o The system must allow certain users to query data from multiple regions.
Development requirements
o When browsing the Products hierarchy, repeating values for different levels of a given
drill-path must be avoided. For example, Papers -> Copy Paper -> Copy Paper ->
Copy Paper should appear simply as Papers -> Copy Paper.
o The system must support report snapshots. The default maximum number of retained
snapshots must not exceed five.
###EndCaseStudy###
You need to develop the executive reports.
What should you do? (Each correct answer presents part of the solution. Choose ail that
apply.)
A.
Provide default values for all parameters.
B.
Set the data source to use Windows authentication.
C.
Remove default values from all parameters.
D.
Implement dataset filters to filter data.
E.
Set the data source to use stored Windows credentials.
F.
Implement dataset query parameters to filter data.
A is ok. Each parameter must have default value. So the report can be executed /prepared automatically. Executive users will use snaphot.
D is ok. If you filter a report, no query is sent to SQL, so you can use snapshot
E is ok. we should use windows credentials where possible. To create snapshot those credentials need to be stored in the report.
