A basic Sybase replication system consists of a primary Adaptive Server Enterprise (ASE) database, a Replication Server®, and a replicate ASE database.
ASE includes all the features necessary to support a Sybase replication system, with no additional components other than the Replication Server.
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.
The Basic Sybase replication system diagram illustrates a basic Sybase replication system, showing the flow of data between two Adaptive Servers and a Replication Server.
Data flows from the primary database to the Replication Server, and then to the replicate database.
For more information about basic Sybase replication system concepts and Replication Server features, see the Replication Server Administration Guide.
