Sybase replication technologies

Sybase provides three replication technologies:

MobiLink is a session-based technology intended for the two-way replication of data between a central, consolidated database and a large number of remote databases. It supports a variety of consolidated database servers, including non-Sybase databases. Administration and resource requirements at the remote sites are minimal, making it well suited to a variety of mobile applications. At the end of each synchronization session, the databases are consistent.
SQL Remote is a message-based technology intended for the two-way replication of transactions. It is designed for two-way replication involving a consolidated data server and large number of remote databases. Administration and resource requirements at the remote sites are minimal, making it well suited to mobile databases. This system is message based. Depending on the setup, typical lag times between the consolidated and remote databases can be on the order of seconds, minutes, or hours.
Replication Server is a connection-based technology intended for the two-way replication of transactions. It is well suited to replication between a small number of enterprise databases connected by a high-speed network, generally with an administrator at each site. In such a setup, it is possible to achieve lag times as low as a few seconds.
