There is an Android tablet app that stores user data in SQLite. And there is a remote MySQL database that stores the data of many users. It is necessary to periodically synchronize or asynchronously synchronize data (mainly from a mobile client to a remote server).
What's the best out-of-the-box solution?
In general, there is no generally accepted remedy. Known:
- Oracle Database Mobile Server + Oracle Database
- Microsoft Sync Framework (SQL Server, SQLite)
- Sybase SQL Anywhere Studio + UltraLite
Of the little-known:
Mobile frameworks like Sencha and RhoMobile also include modules for data synchronization.
