Types of Data Replication in Distribution System
What is data replication? Data replication is the process of storing data in more than one site or node. It is useful in improving the availability of data. It allows users to transfer the same data to different people without any error or deflection. The result is a distributed database in which users can access data relevant to their tasks without interfering with the work of others. It has numerous other advantages, such as, 1. High Availability of Data 2. Improves the performance for retrieval of global queries as the result can be obtained locally from any of the local site 3. Faster execution of Queries 4. Higher availability 5. Reduced latency Data replication is fairly easy when data on a node to be replicated on other nodes doesn’t change. However, replication becomes trickier when data is in constant flux. Moreover, there can be full replication, in which t...
