Data Source Options
In Chapter 11, I introduced data binding and covered a handful of different techniques you can use to display your application’s data on the screen. So far, however, all of the data in Clok has been stored in memory. Test data is loaded when the application is launched, and any modifications to that data are discarded when the application is closed. While that allows us to build an application that looks nice and to work out the details of allowing the user to interact with data, it is not enough to be a usable application.
