A computer system has a plurality of computers each executing stream data processing and a management computer assigning a plurality of divided queries to the plurality of computers. The management computer includes a parameter input module configured to receive an analysis scenario including a plurality of queries and division information for dividing the analysis scenario into the plurality of divided queries; and a query analysis module configured to analyze the analysis scenario to generate a query graph. The query analysis module specifies, based on the analysis scenario and the division information, at least one of the divided queries that requires flow control; and sets the flow control for the plurality of computers to each of which the at least one of the divided queries that requires the flow control is to be assigned. 1. A computer system , comprising:a plurality of computers each configured to execute stream data processing; anda management computer configured to assign a plurality of divided queries including at least one query to the plurality of computers,the plurality of computers each having:a first processor;a first memory coupled to the first processor; anda first interface coupled to the first processor, for coupling to an external apparatus,the management computer having:a second processor;a second memory coupled to the second processor; anda second interface coupled to the second processor, for coupling to an external apparatus;the management computer including:a parameter input module configured to receive: an analysis scenario including a plurality of queries for achieving the stream data processing; anddivision information for dividing the analysis scenario into the plurality of divided queries; anda query analysis module configured to analyze the analysis scenario, to thereby generate a query graph for indicating a structure of the plurality of queries included in the analysis scenario,wherein the query analysis module is configured to: ...
