If you are a current user of CIS, there might not be an advantage to using the HDS feature of Replication Server. Both CIS and Replication Server HDS facilitate replication into a non-Sybase replicate database.
If you are not currently using CIS to communicate with a non-Sybase database, using the HDS feature of Replication Server provides some advantages over using CIS:
Replication system topography is simpler without CIS, and there is no CIS overhead.
You have some greater freedom of component location if you do not use CIS; you are not tied to an existing Adaptive Server location or required to install and maintain another Adaptive Server to decentralize the processing.
The HDS feature of Replication Server does not support replicating to a non-Sybase data server that is not supported by HDS. The HDS feature in Replication Server supports replicate databases only in IBM DB2 Universal Database, Microsoft SQL Server, and Oracle data servers. Any other non-Sybase replicate database requires the use of CIS.
For more information about using CIS, refer to the Component Integration
Services User's Guide, which is part of the Adaptive
Server Enterprise documentation set.
