Recertification for MCSD: Web Applications

 

Topic 1, Olympic Marathon

 

Background

You are developing an ASP.NET MVC application in Visual Studio 2012 that will be used by Olympic marathon runners to log data about training runs.

 

Business Requirements

The application stores date, distance, and duration information about a user’s training runs. The user can view, insert, edit, and delete records.

 

The application must be optimized for accessibility.

 

All times must be displayed in the user’s local time.

 

Technical Requirements

Data Access

Database access is handled by a public class named RunnerLog.DataAccess.RunnerLogDb.

All data retrieval must be done by HTTP GET and all data updates must be done by HTTP POST.

 

Layout

All pages in the application use a master layout file named \Views\Shared\_Layout.cshtml.

 

Models

The application uses the \Models\LogModel.cs model.

 

Views

All views in the application use the Razor view engine.

 

Four views located in \Views\RunLog are named:

 

clip_image002_CalculatePace.cshtml

clip_image002[1]EditLog.cshtml

clip_image002[2]GetLog.cshtml

clip_image002[3]InsertLog.cshtml

 

The application also contains a \Views\Home\Index.cshtml view.

 

Controllers

The application contains a \Controllers\RunLogController.cs controller.

 

Images

A stopwatch.png image is located in the \Images folder.

 

Videos

A map of a runner’s path is available when a user views a run log. The map is implemented as an Adobe Flash application and video. The browser should display the video natively if possible, using H264, Ogg, or WebM formats, in that order. If the video cannot be displayed, then the Flash application should be used.

 

Security

You have the following security requirements:

 

clip_image002[4]The application is configured to use forms authentication.

clip_image002[5]Users must be logged on to insert runner data.

clip_image002[6]Users must be members of the Admin role to edit or delete runner data.

clip_image002[7]There are no security requirements for viewing runner data.

clip_image002[8]You need to protect the application against
cross-site request forgery.

clip_image002[9]Passwords are hashed by using the SHA1 algorithm.

 

RunnerLog.Providers.RunLogRoleProvider.cs contains a custom role provider.

 

Relevant portions of the application files follow. (Line numbers are included for reference only.)
