  • Publication number: 20060041599
    Abstract: A database management system for executing database operations in parallel by a plurality of nodes and a query processing method for it are described. The database management system contains a decision management node for deciding a distribution node for retrieving information so as to analyze a query received from an application program, generate a processing procedure for processing the query, and execute the process and a join node for sorting, merging, and joining the information retrieved by the distribution node. When the query process is executed, the distribution node decided by the decision management node retrieves the information to be processed and the join node decided by the decision management node also obtains the result for the query from the retrieved information. The query result is outputted from an output node and transferred to the application program.

  • Patent number: 5062046
    Abstract: A multiple processor system composed of a plurality of instruction processors allows a plurality of its subsystems for performing data processing in each unit to be operable simultaneously with and parallel to each other in each of the instruction processors. The multiple processor system has a processor designation table and a control processing subsystem. As the processor designation table specifies correspondence relation between a subsystem accessing to each input-output resource and the instruction processor executing the subsystem, the processing control subsystem transfers control of the processing to the instruction processor to be designated by the processor designation table in accordance with the subsystem to be used with reference to the processor designation table during execution of the data processing.
