Introduction

Overview

The Firebase Realtime Database synchronized in realtime to every connected client.

It allows you build cross-platform apps with our iOS and Android, all of your clients share one Realtime Database instance and automatically receive updates with the newest data.

However the current Firebase architecture force the developers to implement a lof of business logic as part of the mobile applications, leading to some side-effects:

• Business logic code duplication among Android, iOS, Windows and all mobile platforms
• Due version fragmentation, business logic is affected by apps being (not) updated.
