title: Mobile database synchronization
body: <p>I have to write an app running on Android, iOS and desktops (I will probably use Titanium). This app has to maintain a database that is constantly synchronized between all devices and desktop (and maybe the web in the future).</p>
  
  <p>Is there any tool/service allowing to do database synchronization very easily?</p>
  
  <p>I want something where I write data locally on any device and data is automatically synchronized and merged using to all devices using the cloud.</p>
