Source : Introduction To Realm Mobile Database In React Native
Nowadays we have a lot of options when deciding to choose a database solution. We have different attractive options each of which has it's strengths and weaknesses. One I have found to be outstanding is Realm database. Realm database can be used by Android, IOS, React and even Xamarin developers.

When Realm was launched in 2014, the goal was to help mobile developers build better apps faster by giving them a robust alternative to SQLite and Core Data. The Realm Mobile Database is a cross-platform database solution that can be used as an alternative to SQLite and Core Data. Compared to these two options, Realm is easier to set up and use. To perform the same operation in Realm, you usually end up writing fewer lines of code than you would with SQLite or Core Data. On performance, Realm is said to be faster and it also offers other modern features such as encryption, JSON support and data change notifications.
