Data processing system, control method therefor, program and information storage medium

A control method for a data processing system,

• the data processing system comprising;
• a first storage that stores original data;
• a data providing device that provides the original data or alternative data with regard to the original data another device, the alternative data being data generated based on the original data;
• a user device;
• a second storage that is different from the first storage;
• and
• a data processing device that is different from the data providing device and that accesses the second storage,
• the control method comprising:
• transmitting, by the data providing device, the original data or the alternative data to the user device through a communication network;
• receiving, by the user device, the original data or the alternative data through the communication network;
• receiving, by the user device, a processing instruction operation performed by a user with the received data as a process target;
• transmitting, by the user device, original data acquisition information to the data processing device through the communication network, the original data acquisition information being information which is used to acquire the original data from the first storage;
• transmitting, by the user device, processing instruction information to the data processing device through the, communication network, the processing instruction information being information relating to a content of the processing instruction operation performed for the process target data;
• acquiring, by the data processing device, the original data stored in the first storage by requesting the data providing device for the original data stored in the first storage based on the original data acquisition information;
• generating, by the data processing device, processed data by processing the acquired original data based on the processing instruction info oration;
• and
• saving, by the data processing device, the processed data to the second storage.

A data processing device that is configured to communicate with a data providing device and a user device,

• the data providing device being configured to provide original data or alternative data with regard to the original data to another device, the original data being stored in a first storage, the alternative data being data generated based on the original data,
• the data processing device being different from the data providing device, being configured to access a second storage different from the first storage, and being configured to acquire and process the original data stored in the first storage,
• the data processing device comprising:
• an original data acquisition information receiving section that receives original data acquisition information in a case where the original data acquisition information is transmitted from the user device, the original data acquisition information is information which is used to acquire the original data from the first storage;
• a processing instruction information receiving section that receives processing instruction information in a case where the processing instruction information is transmitted from the user device, the processing instruction information being information which indicates a content of a processing instruction operation performed on the user device by using the original data or the alternative data as a process target;
• an original data acquisition section that acquires the original data stored in the first storage, by requesting the data providing device for the original data stored in the first storage based on the original data acquisition information;
• a processed data generation section that generates processed data by processing the original data acquired by the original data acquisition section based on the processing instruction information;
• and
• a processed data saving section that saves the processed data to the second storage.

A control method for a data processing device,

• the data processing device being configured to communicate with a data providing device and a user device,
• the data providing device being configured to provide original data or alternative data with regard to the original data to another device, the original data being stored in a first storage, the alternative data being data generated based on the original data,
• the data processing device being different from the data providing device, being configured to access a second storage different from the first storage, and being configured to acquire and process the original data stored in the first storage,
• the control method comprising:
• receiving original data acquisition information in a case where the original data acquisition information is transmitted from the user device, the original data acquisition information being information which is used to acquire the original data from the first storage;
• receiving processing instruction information in a case where the processing instruction information is transmitted from the user device, the processing instruction information being information which indicates a content of a processing instruction operation performed on the user device by using the original data or the alternative data as a process target;
