Case Study: 1<br />

Flight Information<br />

Background<br />

You are developing a flight information consolidation service. The service retrieves flight<br />

information from a number of sources and combines them into a single data set. The<br />

consolidated flight information is stored in a SQL Server database. Customers can query and<br />

retrieve the data by using a REST API provided by the service.<br />

The service also offers access to historical flight information. The historical flight<br />

information can be filtered and queried in an ad hoc manner.<br />

The service runs on a Windows Azure Web Role. SSL is not used.<br />

Business Requirements<br />

• A new data source for historical flight information is being developed by a contractor<br />

located on another continent.<br />

• If a time zone is not specified, then it should be interpreted as Coordinated Universal<br />

Time (UTC).<br />

• When you upgrade a service from a staging deployment to a production deployment,<br />

the time that the service is unavailable must be minimized.<br />

• The default port must be used for HTTP.<br />

Technical Requirements<br />

The existing sources of flight information and the mechanism of exchange are listed below.<br />

• Blue Yonder Airlines provides flight information in an XML file.<br />

• Consolidated Messenger provides flight information in a <strong>Microsoft</strong> Access database<br />

that is uploaded every 12 hours to the service using SFTP. The company uses port 22 for<br />

SFTP.<br />

• Margie's Travel provides and consumes flight information using serialized ADO.NET<br />

DataSets. Data is periodically synced between the service and Margie's Travel.<br />

• Trey Research provides data from multiple sources serialized in proprietary binary<br />

formats. The data must be read by using .NET assemblies provided by Trey Research. The<br />

assemblies use a common set of dependencies. The current version of the Trey Research<br />

assemblies is 1.2.0.0. All assemblies provided by Trey Research are signed with a key pair<br />

contained in a file named Trey.snk, which Trey Research also supplies.<br />

• The application specification requires that any third-party assemblies must have<br />

strong names.<br />
