Abstract: When a distributed processing controller receives a program, which is a job from a terminal unit, a status-confirmation processor transmits a unit processing program and unit data to respective distributed processors A to C registered in a registration table, to select a distributed processor suitable for requesting execution of the program, based on the execution results sent back from the distributed processors A to C.

Abstract: A distributed data processing system uniformly managing distributed data and program files. A resource management database associates identifiers of resource files to be used in analytical processes with their respective storage locations. The identifiers should be unique in the distributed environment, so that all resource files will be uniquely distinguished from each other by using their identifiers. When requesting execution of a particular analytical process, the identifiers specify resource files necessary for the process. A process execution unit in the system first creates a work area, which can also be used to store intermediate data files created during the execution. The resource management database is consulted to know the locations of necessary resource files, and creates links in the work area to reach those files. The process execution unit executes the requested analytical process while making access to the resource files via the links in the work area.
