Persisting data locally using the ApplicationData API and SQLite

While in a lot of cases data can be fetched from the internet, as we have seen in Chapter 4, Mobilizing Your App, there is often a need to persist data on users' devices. This might be the case for data that needs to be available even when there is no internet connection or data that is device-specific such as settings. We will start by persisting small chunks of data using the ApplicationData API.
