Abstract: The present invention serves to produce good performances of the server side regardless of the increase or decrease in the data amount and enables to intercommunicate regardless of the difference in the data format of each client. The application/data transaction management system 1A comprises an application/data transaction management system 1 of the administrator side, a resource provider terminal 21, . . . , 2n, and a user terminal 41, . . . , 4k etc. And the application/data transaction management system 1 of the administrator side has a web server 6, central server 7 etc. and communicates moving image file with the user terminal 41, . . . , 4k. When a communication job is generated, web server 6 etc. determine the dividing aspects of the file in which the processing can be performed at a maximum speed and the computer resource to be processed, and sends the divided moving image file to the predetermined resource provider terminal 21, . . . , 2n. The resource provider terminal 21, . . .
