How to synchronize data in SQL Server transactional replication?
Snapshot publications completely refresh the schema at the Subscriber every time synchronization occurs, so all schema changes are applied to the Subscriber. Transactional replication and merge replication also support the most common schema changes. For more information, see Make Schema Changes on Publication Databases.
How does merge replication work in SQL Server?
When the network connection is established between both database servers, merge replication agents detect changes made on both databases and modify databases to synchronize and update their state. Merge replication is similar to transactional replication, but data is replicated from the Publisher to the Subscriber and inversely.
What are the different types of replication in SQL Server?
