摘要：
In executing query distributed processing in a computer system having a plurality of computers, a query and a sliding window are inherited between different computers. If a tuple having a new principal key value is detected when a query is to be executed, a relevant individual query and a relevant sliding window are inherited between computers, and further a sliding window of a relevant common query is inherited between computers.
