I also go over the various technologies used in the book to build a data persistence layer. In Part 1 of this book, I spend some time talking in general terms about data persistence along with issues specific to mobile app development. SQLite.XM also takes care of organizing your SQL, initializing your apps schema, performing schema updates, and synchronizing data to a server-side datastore. In addition to providing an abstraction layer that greatly simplifies database search and record retrieval. Instead, you app interfaces with a high level, cross-platform layer that provides database CRUD functionality. It shields your application from the details of working directly with SQLite.

SQLite.XM makes using SQLite with Xamarin a snap. SQLite.XM is a freely available SQLite wrapper written in C# and designed to be used with apps developed using Xamarin. 'SQLite Database Programming for Xamarin' will show you how to leverage the power of SQLite.XM to both accelerate and simplify database programming for your mobile applications. However, you still need to learn to effectively use SQLite. This can greatly simplify your mobile development effort. Together, this powerful duo allows you to write a common, shared data persistence layer that works across OS's. Xamarin is the development framework of choice for creating cross-platform mobile apps.

SQLite is the native database for iOS and Android applications.
