The Superpowers of the Realm Mobile Database

The Realm Mobile Database is a new kind of mobile database that’s been built from the ground up to power present-day applications. It’s an easy mistake to think that Realm is built on top of an existing technology, or that it’s just a modern rewrite of another library.

In this series, we’re going to look at a few aspects which set Realm apart from other technologies. If you’ve heard of Realm but don’t know much about what makes it special, these posts are for you.

A technology you would rely on should allow you to be flexible but also help good practices in your own code. In this post we are going to look at how the Realm SDK allows for easy and clean separation of the data, presentation, and view layers of an app.

Part 5: Fine Grained Notifications, Empowering Partial UI Updates

When presenting real-time data in your app you might want to get notified about changes in the underlaying data model with different granularity. Sometimes a simple “the collection has changed” notification is enough, but when you want to do partial updates to your UI, use animations or other effects - Realm’s Fine Grained Notifications are the secret sauce of success.
