Replication is the process of moving changes made to one database to another, similar database. For example, imagine that two different databases contain a Customer table, and that these tables contain identical records for the most part. With replication, changes made to a particular customer record on one database, referred to as the source database, are transferred to the other database, the target database.

There are a number of requirements that must be met before you can implement replication. First of all, replication requires that the source database and the target database both use data dictionaries.

Second, both the source data dictionary and the target data dictionary must be accessed by the Advantage Database Server. Replication cannot be implemented using Advantage Local Server.

Finally, an additional replication license must be installed on the source server—and sometimes the target server as well, depending on how you configure your replication. This license is available from your Advantage representative, and is significantly less expensive than your ADS license.

Replication was added in Advantage Database Server 8.
