Abstract

See full text

A database processing system including a plurality of partitioned databases. Data processing is performed with pieces of information processing apparatus associated with each of the partitioned databases respectively. In response to a query, a status table indicating availability of each information processing apparatus is read from the storage. Of the pieces of information processing apparatus for processing the received query, at least a serviceable one is determined as a process request destination. A process request corresponding to the query is transmitted to the information processing apparatus determined as the process request destination. The process request is received through a communication unit, and data on the database are consequently processed. A processing result is transmitted to a transmitting source through the communication unit.
