As of ColdFusion 9 you have the ability to create database driven applications by writing virtually no SQL statements using ORM. You can use this server-side feature on the client-side in an AIR application. This session will talk you through the basics of using ColdFusion ORM in AIR and how to "automagically" synchronise your local data with a remote ColdFusion 9 server. That's not all: we'll go one step further and take that ability to create database driven applications onto the mobile platform as well. Just like that.
