Microsoft SQL Server Replication is a data synchronization technology that allows data to be copied and distributed from one database to another. It is used to improve the availability, scalability, and performance of databases in a distributed environment.
There are several types of replication that can be used depending on the specific needs of an organization, including:
1. Snapshot replication: This type of replication distributes a copy of the entire database at a specific point in time. It is useful for data that does not change frequently.
2. Transactional replication: This type of replication distributes changes made to the database as they occur. It is useful for data that changes frequently and requires near real-time synchronization.
3. Merge replication: This type of replication combines changes made to the database at different locations and merges them into a single database. It is useful for distributed environments where multiple users can modify the same data.
SQL Server Replication can be used to support scenarios such as reporting, disaster recovery, and high availability. It is a powerful tool for managing data synchronization across distributed environments.
