Abstract
In one aspect, a computerized method useful for operating a database management system DMBS DBMS in a strong consistency mode comprising includes the step of implementing an atomic transfer of a master node of the DMBS DBMS. The method includes the step of implementing a master node restriction, wherein the master node restriction guarantees no more than one master node is ever available. The information about a set of nodes participating in a cluster of the set node of the DMBS DBMS is maintained to allow a subset of nodes to determine that the one master node is a master of a subset of data stored in the cluster.
