How can I have开发者_如何学Go database connectivity for HTML5 for mobile applications to store data on a web server?

For now, I am trying for an Android device, but I will also be using it for iPhone. I am using the Eclipse editor.

The most typical way to do this is to build a web service that acts as a frontend for the data you want to store.

You will have to create website which can accept and process some data, potentially persisting, modifying or retrieving from a database, and access this website from the app's code.

Providing direct access to a database to arbitrary users would be very unwise.
