Ideas of creating a distributed computing cluster (DCC) for database management systems (DBMS) have been striking me for quite a long time. If simplified, the DCC software makes it possible to combine many servers into one super server (cluster), performing an even balancing of all queries between individual servers. In this case, everything will appear for the application running on the DCC as if it was running with one server and one database (DB). It will not be dispersed databases on distributed servers, but work as one virtual one. All network protocols, replication exchanges, and proxy redirections will be concealed inside the DCC. At the same time, all resources of distributed servers, in particular RAM and CPU time, will be utilized evenly and in an efficient fashion.

For example, in a cloud data processing center (DPC), it is possible to take one physical super server and divide it into a number of virtual DBMS servers. But the reverse procedure was not possible until now, i.e., it is not possible to take a number of physical servers and merge them into a single virtual DBMS super server. In some specified sense, DCC is a technology that makes it possible to merge physical servers into one virtual DBMS super server.
