The City 311 Demo App shows how a mobile application that communicates with an Adabas/Natural application can be used to provide 311 services. 311 is a non-emergency phone number that citizens can call in many communities in the US and Canada and that provides access to municipal services. In this sample project, webMethods Integration Server and EntireX are used as middleware, and webMethods Mobile Suite is used to provide the necessary mobile capabilities of mobile enterprise application platforms for application development and deployment.
