Use transaction replication to maintain data in separate databases called replicate databases. Replicate databases contain accurate, current copies or subsets of data from a primary database.
When a table in the primary database is marked for replication, transactions that change the data in that table are captured for replication. The primary database processes the transaction, and a copy of the transaction (including all its operations) is stored in the transaction log.
In the case of a stored procedure marked for replication, when the stored procedure is invoked in the primary database, all parameter values provided with the procedure invocation are captured and recorded in the transaction log. When a marked stored procedure generates a transaction that affects data in marked tables in the primary database, the transaction generated by the stored procedure is ignored, so only the procedure invocation is replicated.
