Information processing apparatus providing data transfer support system, and data transfer method

An information processing apparatus configured to provide a data transfer support system that works in cooperation with a data transfer service, the information processing apparatus comprising:

• a memory storing instructions;
• and
• a processor executing the instructions causing the information processing apparatus to:
• receive, from the data transfer service, data that is sequentially output by the data transfer service based on collective acquisition from a first database of a transfer source system, wherein data stored in the first database is managed as a plurality of related tables, and the data managed in the plurality of related tables includes data that requires sequence control for registration of data in a third database of a transfer destination system;
• execute storage processing to sequentially store the received data in a second database for use during a transfer process, by the data transfer support system, wherein the second database is different from the first database and the third database;
• acquire, asynchronously to the storage processing, the data from the second database;
• determine whether the data acquired from the second database satisfies a condition;
• register the acquired data with the third database in the case in which the data that has been acquired from the second database satisfies the condition;
• re-register the acquired data with the second database in the case in which the data that has been acquired does not satisfy the condition, wherein the data re-registered with the second database is re-acquired for registration with the third database based on the condition;
• and
• manage a mapping data that associates identification information that has been issued by the third database with identification information prior to registration in the third database,
• wherein, when information referenced by the data acquired from the second database contains identification information, in the case in which the identification information issued by the third database associated with the identification information prior to the registration in the third database is managed by the mapping data, the processor determines that the data acquired from the second database satisfies the condition and registers the acquired data with the third database, and in the case when the identification information issued by the third database associated with the identification information prior to the registration in the third database is not managed by the mapping data, the processor determines that the data acquired from the second database does not satisfy the conditions and re-registers the acquired data with the third database.
