1. In a parallel-processing based database management system comprising a plurality of interconnected processing nodes, a method for configuring a system for processing queries, the method comprising: distributing software to each processing node of a first subset of the plurality of processing nodes; distributing a master node configuration file to a processing node of the first subset designated as a master node of a first global-results processing matrix; distributing a slave node configuration file to each processing node of the first subset designated as a slave node of the first global-results processing matrix; manipulating, by the software and master node configuration file, the designated master node to operate as the master node of the first global-results processing matrix; manipulating, by the software and slave node configuration file, each of the designated slave nodes to operate as a slave node of the first global-results processing matrix; receiving a query in a query-based language source code and compiling at least one executable from the query source code; and executing, by the configured global-results processing matrix, the compiled at least one executable to process a query.
