Pranay Airan - Forget SQLite and say hello to Realm

Forget SQLite with no SQL database designed for mobile. Realm is not an ORM on top of SQLite. Instead it uses its own persistence engine, built for simplicity & speed. A true cross platform solution that replaces sqllite and core data on android and iOS.

Most android apps requires a persistance storage to provide caching and offline functionalities in the app. Currently there are very limited options avialble for persitance storage, most people rely on SQLite or file storage. If app’s backend is no sql there is an additional overhead of conversion with SQLite. SQLites api’s on android are complicated, most people in turn uses additional ORM layer on the top adding additional complexity.

In this talk we will be talking about Realm, how to use it in your app, perfomrance comparison for read, write, updates. Some pros and cons of using Realm vs sqllite. We will also be comparing realm agains CouchDB Lite another no SQL database for mobile from CouchDB team.
