There are four important things to note in the code snippet above: You may want to read both if you aren’t familiar with the concepts.

An exciting tidbit of information is that SQLite is the most used database engine in the world, and quite possibly the most widely deployed software ever. In fact, in Android, device contacts, and media are stored and referenced using SQLite databases. SQLite is native to both Android and iOS, and every app can create and use an SQLite database if they so desire. What this means is that you can bundle a SQLite database with your application, and get access to all the power of a relational database within your application. Rather, it is embedded into the end program. It implements most of the SQL standard, but unlike the four database engines mentioned above, it is not a client-server database engine. SQLite is a relational database management system, similar to Oracle, MySQL, PostgreSQL and SQL Server. In this tutorial, I delve into how to use an SQLite database in more detail. However, due to article length constraints, I could not adequately cover creating and using an SQLite database for data persistence. I recently published a tutorial describing the different available methods to store data locally in an Android app.
