Develop a DCM methodology and replication topology

You will need to develop a plan for the flow of information between databases before you can use DCM effectively. A DCM methodology defines what information is replicated between which databases. A replication topology defines whether the databases replicate data directly with each other, or through intermediate hub databases.

The contents of transfer packages are not addressed by the DCM methodology. Transfer packages are part of the implementation of the methodology and are controlled by each source database.

Note: Within a given DCM cluster, different software components can use different methodologies. For example, an application that is being developed across multiple sites might use the Master and Satellite methodology. In the same cluster, however, a software feature that is shipped as a tested released component might be transferred using the Publish and Subscribe methodology.
