A basic Sybase replication system consists of three components:
Primary database – a database in which original data-changing operations (or transactions) are performed. Only completed transactions are captured for replication.
Replication Server – a Sybase Open Client™ and Open Server™ product that receives transactions to be replicated from a primary database, and delivers them to a replicate database.
Replicate database – a database that receives replicated transactions from a Replication Server and applies those transactions to its own “copy” of the primary data.
If both primary and replicate data servers are Adaptive Server Enterprise (ASE), you can implement a replication system with only these three components. Adaptive Server Enterprise includes all the features necessary to support a Sybase replication system, with no additional components other than the Replication Server.
Figure 1-1 illustrates a basic Sybase replication system, showing the flow of data between two Adaptive Servers and a Replication Server.
