ReplicationDatabase can be used to represent a publication or subscription database. ReplicationDatabase cannot be used to represent system databases, such as master, tempdb, msdb, and model. A distribution database is represented by DistributionDatabase.

This example creates the distribution database when the Distributor is installed. It also enables merge and transactional publishing on the AdventureWorks database.
