I found the best thing for me was to create a WCF Service Library, and then use LINQ to SQL - the json is created for you automatically, and the server side code is nice and easy.
The only downside is that this requires .NET 4, but it will operate on IIS 6.
There are a couple of things to be mindful of when dealing with dates, but its all pretty straightforward.
Thank you for your answers. I have another question about this. Is there any e-commerce app builded with sencha touch? Because we want to create an app including credit card payment etc.

Yes sure, I have done an e-commerce app with Sencha, took me some time but now it works great.
The tricky step is to integrate the payment part so you should check what kind of payment modes you're going to allow first. (Paypal works well for instance)
