Terminal device and data management method

A terminal device comprising a plurality of processing devices, wherein the processing devices each includes:

• a database;
• state managing circuitry to manage data stored in the database;
• request managing circuitry to determine data to request from an external system and an order in which the data is to be requested from the external system on the basis of a management state of the data in the state managing circuitry, a management state of data in a state managing circuitry of another processing device, and a type of predetermined event requiring data in a case where the predetermined event has occurred, the request managing circuitry being capable of requesting data from the external system on the basis of the order;
• and
• obtainment managing circuitry to manage a state of obtainment of data from the external system, wherein
• the request managing circuitry generates a first request queue indicating the data to request from the external system and the order in which the data is to be requested on the basis of the management state of the data in the state managing circuitry and the type of predetermined event,
• the request management circuitry obtains, from another processing device, a first request queue generated on the basis of a management state of data in the other processing device and a type of predetermined event requiring data in a case where the predetermined event has occurred, and
• the request management circuitry combines the generated first request queue with the obtained first request queue to generate a second request queue indicating data to request from the external system and an order in which the data is to be requested by the terminal device, and
• request managing circuitry of a predetermined processing device requests data from the external system by using the second request queue.
