Both MobiLink and SQL Remote provide data synchronization between a central database and a set of remote databases.
In MobiLink, the consolidated database is one of several supported RDBMSs. The consolidated database, which typically resides on a corporate server, tracks synchronization information and optionally contains the data to be replicated. Other central data may be stored in any other format, such as a non-relational database, web service, or text file.
MobiLink also provides direct row handling, which enables data synchronization to consolidated data sources other than relational databases including enterprise resource planning (ERP) systems or application servers.
In SQL Remote, all data that is to be synchronized is contained in a SQL Anywhere consolidated database.
A remote database can run either at the same site as the consolidated database or at a physically distant site such as a handheld device. The remote database can share all or some of the data in the consolidated database.
The following figure displays a schematic illustration of a small synchronization system.
