Case Study 2 - ASP.NET MVC (QUESTION 49 - QUESTION 63)

Background
You are developing an ASP.NET MVC application in Visual Studio 2012 that will be used to
process orders.
Business Requirements
The application contains the following three pages.
- A page that queries an external database for orders that are ready to
be processed. The user can then process the order.
- A page to view processed orders.
- A page to view vendor information.
The application consumes three WCF services to retrieve external data.
Visual Studio Solution:
The solution contains the following four projects.
- ExternalQueue: A WCF service project used to communicate with the
external order database.
- OrderProcessor: An ASP.NET MVC project used for order processing and
logging order metadata.
- OrderUpload: A WCF service project used to submit order data to an
external data source.
- Shipping: A WCF service project used to acquire shipping information.
ExternalQueue Project:
Entity Framework is used for data access.
The entities are defined in the ExternalOrders.edmx file as shown in the following diagram.

The project contains two services defined in the following files.

- IExternalQueueService.es
- ExternalQueueService.svc.
The ExternalQueue.Helpers namespace contains a definition for a class named OrderNotFound
Exception.
OrderProcessor Project:
The entities are defined in the ProcessedOrders.edmx file as shown in the following diagram.
The classes are contained in the OrderProcessor.Entities namespace.

The project contains the following two controllers.
- InboundQueueController.es
- ProcessedOrderController.es
WCF service proxies to the ExternalQueue, Shipping and OrderUpload services have been
generated by using the command prompt.
The ExecuteCommandProcedure() method in the ExternalQueueService.svc file must run
asynchronously.
The ProcessedOrderController controller has the following requirements.
The GetVendorPolicy() method must enforce a 10 minute absolute cache expiration policy.
The GetProcessedOrders() method must return a view of the 10 most recently processed orders.

OrderUpload Project:
- IUploadCallbackService.es
- UploadCallbackService.svc
Data Access is maintained in a file named UploadOrder.es.
Shipping Project:
The entities are defined in the ExternalOrders.edmx file as shown in the following diagram.
The Custom Tool property for ExternalOrders.edmx has been removed. POCO classes for the
Entity Model are located in the ShippingAddress.es file.
The POCO entity must be loaded by using lazy loading.
- IShippingService.es
- ShippingService.svc.
The IShippingService contract must contain an operation that receives an order number as a
parameter.
The operation must return a class named ShippingInfo that inherits from a class named State.

Case Study 3 - Online Bookstore (QUESTION 64 - QUESTION 78)

Background
You are developing an online bookstore web application that will be used by your company's
customers.
General requirements:
- The web store application must be an ASP.NET MVC application written
in Visual Studio.
- The application must connect to a Microsoft SQL database.
- The GetTop100Books() method is mission critical and must return data
as quickly as possible.
It should take advantage of fast, forward-only, read-only methods of
reading data.
- The ImportBooks() method must keep a copy of the data that can be
accessed while new books are being imported without blocking reads.
- The Create MonthlyTotalsReport() method must lock the data and
prevent others from updating or inserting new rows until complete.
- The college textbook area of the web application must get data from a
daily updated CSV file.
- The children's book area of the web application must get data
directly from a local database.
It must use a connection string. It must also support access to the
stored procedures on the database. Further, it is required to have
strongly typed objects. Finally, it will require access to databases
from multiple vendors and needs to support more than one-to-one mapping
of database tables.
- The cookbook functionality is contained within a client-side
application that must connect to the server using HTTP and requires
access to the data using JavaScript.
- The BookApiController class must have a method that is able to
perform ad-hoc queries using OData.
The RESTful API of the bookstore must expose the following endpoints.

LINQ to SQL
Entity Framework
ADO.NET
Answer: A
Explanation:
* Scenario: The cookbook functionality is contained within a client-side application that must
connect to the server using HTTP and requires access to the data using JavaScript.
* WCF Data Services (formerly known as "ADO.NET Data Services") is a component of the .NET
Framework that enables you to create services that use the Open Data Protocol (OData) to
expose and consume data over the Web or intranet by using the semantics of representational
state transfer (REST). OData exposes data as resources that are addressable by URIs. Data is
accessed and changed by using standard HTTP verbs of GET, PUT, POST, and DELETE
* WCF Data Services uses the OData protocol for addressing and updating resources. In this
way, you can access these services from any client that supports OData. OData enables you to
request and write data to resources by using well-known transfer formats:
Atom, a set of standards for exchanging and updating data as XML, and JavaScript Object
Notation (JSON), a text-based data exchange format used extensively in AJAX application.

deploy relational database solutions to the cloud, and take advantage of a distributed data center
that provides enterprise-class availability, scalability, and security with the benefits of built-in data
protection and self-healing.
Session States in Windows Azure.
If you are a Web developer, you are probably very familiar with managing user state - that is you
are familiar with tracking user activity and actions across several request-response exchanges
that occur in Web applications. Since HTTP is a stateless protocol, developers over the years
have developed all sorts of means to manage state. You'll even find an MSDN page providing
alternatives and recommendations for state management here. Cookies, hidden fields, and query
strings are some client-side options to tracking user state. When it comes to managing that state
on the server-side, most Web developers rely on session objects.
