Chapter 6. Getting Data In

One of the key aspects of any application is the handling of data—getting data into the application so that you can manipulate and store it, and then getting it out again for display. We will spend the next two chapters covering data handling in Sencha Touch. This first chapter on data will focus on getting data into your application.

We will start with a discussion of the data models that are used to describe your data. We will then talk about readers that gather the data and the stores used to hold the data for use in our application. Once we have a grasp on where the data goes, we will cover how to use forms to get it there. We will look at how to validate your data and provide you with some examples of form submission. We will finish up with a look at getting the data back into a form for editing. This will serve as our starting point for the next chapter on data, which will cover getting data back for display.
