Realm Is the Best Android Database Solution
Since the inception of the platform, Android developers have had pretty much only one option for a database: SQLite. Although feature-rich and powerful, it wasn’t quite what Android app developers needed. Realm, a modern, efficient database solution for mobile platforms, turned out to be an amazing replacement for SQLite on Android.
In this article, Toptal Software Engineer Mateus Gondim Romão Batista explains why you should use Realm for your next Android application.
