Topic 3, Online Bookstore
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.
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.

Topic 2, ASP.NET MVC
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 classnamed State.

###EndCaseStudy###

The UploadOrder() method in the UploadCallbackService service is not implementing the
callback behavior defined in the IUploadCallBackService interface.
You need to modify the class to implement the required callback behavior.
