The more I look at Sencha the more impressed I am. For instance, the capabilities outlined in Sencha.io video are amazing. Those sync and messaging options would save me a lot of coding time.
But what db does Secha Touch and Ext JS use? MySQL? ProstgreSQL?
Or a it's own proprietary db?
Also, in the video the John said something to the effect that for the time being, there is no cost, but eventually usage fees would be involved, depending on the application and bandwidth.
I fine with that, but does this mean that Sencha is hosting Ext JS apps?
