What type of database replication relies on centralized control that determines when replicas may be created and how they are synchronized with the master copy
Database replication is very common in this Era. Traditional database replication is relies on centralized control that determines when replicas may be created and how they are synchronized with the master copy.
Database replication is known to be the constant electronic copying of data from a database using one computer or server that is connected also to a database in another . this ensure that all users do share the same level of information.
Replication is often done to technologies which are used for copying and distributing data and database objects from one database to another and thereafter use in synchronizing between databases.
Conclusively, Replicas can only be made in the Traditional database replication through the power of centralized control.
