are two “big picture” methods of doing sync. One is a
Document sync (Think like a gallery with videos and
pictures). Documents are saved, the whole document is sent
to the server, then the whole document is pushed out to
other clients who are syncing against the same source. The
other is a Transactional sync where many small atomic
operations are sent to the server. The best analog I have
is Google Drive/operation transforms. </span></p>

the application have to be opened (foreground) for syncing
to happen? As far as I know, native Web requires this
(barring extensions to the browser, plugins etc). I think
Cordova can in Android, but I haven’t researched it. iOS
seems like a mixed bag, but generally you can only sync if
your application is in the foreground (but you can use
notifications and badges to communicate that there is a
pending sync or new data). I understand there is CoreData +
iCloud that is supposed to do something, but that seems like
it is still foreground only. On Android background sync is
easy.</span></p>
