Ross and Rachel Terman of XEQ Information Solutions presented on their HTML5, JavaScript, CSS, and web services application. They discussed the application's components including the SQL database, .NET web service, HTML5 pages, CSS stylesheet, and JavaScript files. They explained how the application follows the MVC2 pattern with model classes mapped to the database, a controller in the web service, views as HTML pages, and view controllers as JavaScript files. They then demonstrated the application and provided resources for further learning on HTML5, CSS, and web development.
