  1. Microsoft SQL Server Replication – The Functionalities Replication technology is the process that copies and distributes database objects from one database to another and helps to distribute data to various locations for remote and mobile users. The replication activity is carried out over the Internet, dial-up connections, wireless connections, and local and wide area networks.

  2. In the past, when enterprises worked on a single server for multiple users working in various locations, they faced performance and availability problems and maintenance issues. After the introduction of SQL real time replication, specialized tools help to maintain database copies at multiple locations.  

  3. SQL real time replication enhances the performance of SQL Server databases and information availability in businesses. It thereby ensures that data can be integrated and loaded into data warehouses, migrated to cloud storage platforms, and finally, copied and distributed across multiple database servers in remote locations. These activities are regardless of whether a third-party strategy is created by a replication expert or the process is implemented using built-in MSSQL replication utilities.

  4. SQL real time replication also makes sure that data-driven enterprises integrate data in real-time and realize faster time-to-insight. This is possible because changes and updates that are made by individuals at various locations are synchronized to the main server quickly. SQL real time replication distributes the relevant part of the tables and views only and not the entire database. Enterprises can also accelerate, supplement, and lower the cost of SQL real time replication using SQL change data capture technology (CDC).

  5. There are three types of SQL real time replication.The first is Snapshot Replication where a “snapshot” of the data in one server is taken and then moved to another server or another database in the same server. After completing the first synchronization, the replication process refreshes the data in published tables at pre-set intervals.

  6. The second type of SQL real time replication is Transactional Replication. Here, it starts with the first Snapshot Replication. In the second step, the data is copied once from the publisher to the subscriber/s and then all transactions are delivered to the subscriber/s as and when they take place on the publisher. The benefit of this type of SQL real time replication is that by making a small change in the configuration, transactions can be delivered continuously.

  7. Finally, there is the Merge Replication where the SQL real time replication tool merges data from multiple sources into a single central database. Here too, the replication process begins with the Snapshot Replication and allows changes of the data on publishers and subscribers offline. When connectivity to the network is restored, the tool combines changes from all subscribers and changes data on the publisher accordingly.

  8. Summing up, with SQL real time replication, it is possible to replicate and merge data from transactional databases to Microsoft SQL Server quickly and seamlessly. Enterprises can also integrate data from other sources with data from transactional databases for real-time reporting.Click here to learn more.
