Replication Technologies


About this chapter 

Data replication is the sharing of data among physically distinct databases. When an application modifies shared data at any one database, the changes are propagated to the other databases in the replication setup. Changes can be propagated by various means and through a variety of channels, allowing flexible replication setups while preserving data integrity. Data replication is also referred to as data synchronization.

Sybase has three replication technologies. MobiLink and SQL Remote are designed for replication between a central database and a large number of remote databases. Replication Server is intended for near-real-time replication between a relatively small number of databases.
