I need to sync my Android SQLite DB with my cloud-server DB, and doing it in a bi-directional way in a multiuser environment.
I have found and introduction to the solution here but I would like to read about a better solution/algorithm.
Can you use Oracle Database as your server-side DB?
If so, you should consider Oracle Database Lite, which includes a full synchronization solution that is compatible with SQLite and Android, and was designed for multi-user environments.
It supports automatic synchronization, advanced conflict resolution, and multiple sync models. It also supports deploying and managing apps from a central management console, and even device management.
You can read more about it here: http://www.oracle.com/technetwork/database/database-lite/overview/index.html
Also, you can click on the download tab to try it out for yourself.
