AI Technical Summary

Technical Problem

In existing technologies, transaction synchronization between peripheral and core systems in banking systems is unreliable and cannot meet the requirements for high timeliness, especially when transaction results are not accepted.

Method used

The method adopts active query and batch synchronization. When the transaction application status from the external system to the core system is unknown, an online query request is initiated every preset time period, and the status is updated before the preset deadline. After the deadline, transactions in the unknown status are synchronized in batches by receiving the end-of-day transaction text from the core system.

Benefits of technology

It achieves efficient and reliable synchronization of transactions between the peripheral system and the core system, meets the requirements of high timeliness, and is suitable for transaction synchronization under various abnormal conditions.

Abstract

This invention discloses a transaction synchronization method and peripheral system based on proactive querying and batch synchronization, applicable to the financial field or other fields. The method includes: determining the status of transaction requests initiated by the peripheral system to the core system; when the status of the transaction request is determined to be "unclear," for transactions with an "unclear" status, initiating an online query request to the core system every preset time interval; if the query is successful before a preset deadline, updating the transaction request status to "clear"; after the preset deadline, for transactions whose status remains "unclear" after the online query request, batch synchronizing the transaction request status of the peripheral system by receiving the end-of-day transaction text from the core system. This invention can efficiently and reliably synchronize transactions between the peripheral system and the core system based on proactive online querying and batch synchronization.
