In the Master and Satellite methodology, one DCM database
is designated as the master. All other databases
in the cluster are called satellites. The master
performs master builds that combine changes made in the satellites.
A Master and Satellite methodology is used when software
components of an application are developed in different databases,
but must be built, tested, and released together.
Typically, the satellites replicate directly with
the master using point-to-point transfers. Satellites can replicate
with each other:
- Directly using a Point-to-Point topology
- Provides the quickest propagation of changes from
satellite to satellite.
- Indirectly through one or more hub databases
- The master database is often the hub around which
the satellites form the spokes.
