Background
You are developing an online bookstore web application that will be used by your company’s customers.
Technical Requirements
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.
TheGetTop100Books()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.
TheImportBooks()method must keep a copy of the data that can be accessed while new books are being
imported without blocking reads.
TheCreateMonthlyTotalsReport()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 a 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.
TheBookApiControllerclass must have a method that is able to perform ad-hoc queries using OData.
The RESTful API of the bookstore must expose the following endpoint.
Action: Get a list of all books
HTTP method: GET
Relative URI: /books
Action: Get a book by id
HTTP method: GET
Relative URI: /books/id
Action: Create a new book

Testlet 1
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.
Technical Requirements
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:
Entity Framework is used for data access. 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:

The project contains two services defined in the following files.
IUploadCallbackService.es
UploadCallbackService.svc
Data Access is maintained in a file named UploadOrder.es.
Shipping Project:
Entity Framework is used for data access. 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.
The project contains two services defined in the following files.
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.
