SQLite is a lightweight, embedded relational database management system that is included as part of the Android framework and provides a mechanism for implementing organized persistent data storage for Android applications. When combined with the Room persistence library, Android provides a modern way to implement data storage from within an Android app.
The goal of this chapter was to provide an overview of databases in general and SQLite in particular within the context of Android application development. The next chapters will provide an overview of the Room persistence library, after which we will work through the creation of an example application.
