If you're looking for a SQL Server database replication tool that offers flexibility and ease of use, we encourage you to consider Qlik Replicate (formerly Attunity Replicate) in your database replication tool comparison. Implement SQL Server Database Replication More Easily and With Greater Flexibility When publisher and subscriber are connected, a merge replication agent detects changes on both systems and modifies each system accordingly. Transactional replication, which is the most common SQL Server database replication type, delivers a near real-time copy of individual database transactions from the publisher to the subscriber(s) when changes to the publisher are detected by a replication agent.Ī type of bidirectional SQL Server replication, merge replication is typically used in server-to-client environments to synchronize data across systems which cannot be continuously connected. Snapshot replication is a single unidirectional push of all data and database objects from the source database, referred to as the publisher, to the target database, or subscriber. Through embedded SQL database replication technology, SQL Server supports three types of replication: snapshot, transactional, and merge replication. SQL Server Database Replication: Replication Types Supported by SQL Server Data replication is one of the three primary data integration use cases. SQL Server replication can be run continuously or at predetermined intervals and data synchronization can be based on four main approaches: bi-directional, one-way, one-to-many, and many-to-one.
SQL Server database replication refers to a set of technologies which copy and distribute data and objects from one database to another and maintain consistency and integrity between these databases through synchronization.
