Replicated transactions are published by table. When data-changing operations affect the contents of a published table in the primary database, they are recorded for subsequent distribution to a replicate database.
A replicate database can be a subset of a primary database, with some, but not all of the tables in the primary database. Therefore, not all of the tables in a primary database have to be published.
To receive replicated transactions, the replicate database must subscribe to a published table in the primary database, and it must identify the subscribing replicate database table. Replicated transactions from the primary database are distributed to subscribing tables in the replicate database.
