MobiOne is great for laying out a mobile UI quickly but it does not extend to integrating arbitrary enterprise services. For example if you want to interface with mysql you will not do that directly from a mobile app. A multi-tiered architecture is required that involves a web access layer between your app and your database. To even start on such a system you need a web service that will interact with your database. Also you need a secure connection (https) from your app to your web service. To make all this go you need a web server, scripting language such as php to create your web services and javascript to perform the login from your app to your web service. My recommendation is before dicking around with a mobile app is to implement this use-case simply in php. I say this because if you can’t get that simpler scenario going you’ll never have success with a mobile app. There a tons of php tutorials and example code that you can access from a google search. Give it a go a let us know once you have the server side infrastructure in place and tested.
