The technology advancements are never ending. Various technologies are being introduced into the market to help ease access and improve the overall performance of a company. One of such advancements has been seen in replication technology. This is a reliable server resource that is proving indispensable for companies looking for absolute servicer reliance.
The Replication technology allows for the copying and distributing of data and database objects between databases. The software also synchronizes the databases to ensure consistency. Companies embracing this technology are able to distribute data via local and wide area networks, wireless connections, and dial-up connections and over the Interne. This is an advancement that has brought about great reliance when it comes to the handling of data. Microsoft SQL Server has been determined to be the best solution when it comes to this.
According to recent reports, Replication has been found essential when it comes to data warehousing, improved scalability as well as availability. The Microsoft SQL replication involves the subscriber, distributor and the publisher. In this case, the publisher offers data for distribution while the distributor is basically the intermediary in publishing. Subscribers are consumers of the data provided by the publisher. There are basically three replication models.
Snapshot Replication
This is a model that takes a snapshot of the publication and then makes it available to the subscribers. This is a one shot deal. There is no continuous data stream from publishers to subscribers. The data is updated through intervals; only when a snapshot is taken.
Transactional Replication
This is the second model that involves frequent data changes. This is used where databases change frequently and the databases require constant refreshing. This option allows for faster synchronization of data with little latency. This is a reliable option where updates to subscribers is needed fast.
Merge Replication
This is a common option where there is no constant connectivity between the publishers and the subscribers. The model enables the sites to work autonomously. The data is only changed when a connection is established between the two parties.
The Microsoft SQL Server has a number of reliable capabilities that makes it a great option for users. However, it is important to understand the various limitations that the same replication system faces. The challenges are, however, limited to the selected version.
According to the experts, users of Replication technology should choose the model that best meets their needs. Some options are incomprehensive and could lead to poor performance.
