    $(document).ready(function(){

    $(quot;#sliderquot;).slider();

    });

    Now, when you run this page then you will see a long slider on page with no range. As we have not specified any range.slider control comes with various options/properties which can be set. Here are few of them.

    1. min : Minimum value allowed for the slider.

    2. max : Maximum allowed value for the slider.

    3. step : How much you want to increment when you slide. Default is 1.

    4. value : set default value of the slider.

Topic 5, Flight Information Background

You are developing a flight information consolidation service. The service retrieves flight information from a number of sources and combines them into a single data set. The consolidated flight information is stored in a SQL Server database. Customers can query and retrieve the data by using a REST API provided by the service.

The service also offers access to historical flight information. The historical flight information can be filtered and queried in an ad hoc manner.

The service runs on a Windows Azure Web Role. SSL is not used.

Business Requirements

->A new data source for historical flight information is being developed by a contractor located on another continent.

->If a time zone is not specified, then it should be interpreted as Coordinated Universal Time (UTC).

->When you upgrade a service from a staging deployment to a production deployment, the time that the service is unavailable must be minimized.

->The default port must be used for HTTP.

Technical Requirements

The existing sources of flight information and the mechanism of exchange are listed below.

->Blue Yonder Airlines provides flight information in an XML file.

->Consolidated Messenger provides flight information in a Microsoft Access database that is uploaded every 12 hours to the service using SFTP. The company uses port 22 for SFTP.

->Margie#39;s Travel provides and consumes flight information using serialized ADO.NET DataSets. Data is periodically synced between the service and Margie#39;s Travel.

->Trey Research provides data from multiple sources serialized in proprietary binary formats. The data must be read by using .NET assemblies provided by Trey Research. The assemblies use a common set of dependencies. The current version of the Trey Research assemblies is 1.2.0.0. All assemblies provided by Trey Research are signed with a key pair contained in a file named Trey.snk,

which Trey Research also supplies.

->The application specification requires that any third-party assemblies must have strong names.
