![]() OO model makes it 10x faster than SQLite and saves you from running tons of query which is a common thing for a typical SQL database. ![]() Realm is an object-oriented database rather than a relational database. Realm allows developers to undergo frequently mapping classes, tables, foreign keys or the fields. That explains why developers prefer to use Realm while handling a large amount of data or for high-performance applications. Realm is not an ORM or built on top of SQLite, it has its own database engine and doesn’t just rely on key-value stores. Realm database was built from scratch for offline and real-time applications running on mobile and wearable devices. The local databases considered in our evaluation are listed below: We will first start with local databases. Local database selection for react native apps We have hand picked everything you need to know in order to select the right database for your react native app development. Because of which they struggled with the releasing new features, and could neither implement complex business logic to local and server side database. From an infinitely scalable database Firebase became a living nightmare for them. Recently Crisp, a live-chat startup, who built their hybrid application using Firebase had to switch after few months of release. Poorly chosen Database can lead to failures for your React Native application. Now, there are many databases available for React Native which offer offline sync, reliable performance, better security and tons of new-edge features. To meet these challenges they have to choose the right technology stack including the platform, back-end framework, libraries and a database. Moreover, there is a pressure on developers to deliver offline-first and high performing application that can be scaled whenever needed. From established organizations to hot new startups, developers are using React Native to build cross-platform applications.
