A method and system for keeping data consistency

Abstract

This invention discloses one method to keep link data interacting accordance, which comprises the following steps: delivering data interacting requires through customer end to trigger mutual platform to generate only relative interacting order number and to inform servo; the said servo fulfills data process and feeding back results with plat recording the process information to first list; if it fails, then starting rolling operation require and recording the operation information by second information list to feed back close information.

Description

technical field [0001] The invention relates to the field of network-based online data interaction, in particular to a method and system for maintaining data consistency in online data interaction. Background technique [0002] The basic feature of online data interaction is that the client processes data input and output and basic preprocessing, the server performs specific data processing, and the data interaction between the client and the server needs to be realized through an interactive platform. The interactive platform is used to save Process information for data interaction. Specifically, the process of data interaction is: the client accepts the user's request, makes a request to the server through the interactive platform, the server obtains the data from the database, processes or calculates the data, and submits the result to the client through the interactive platform. At the same time, the interaction platform records the process information of data interacti...

Problems solved by technology

The above four processes may cause transmission failures due to network or hardware failures. For example, on the server, the transaction has been processed or completed; on the client side, no response is received, so the transaction fails, resulting in The transaction between the server and the client is incomplete, and the data is inconsistent

[0005] In addition, the existing bank online transaction processing system often involves multiple bank host systems. When the transaction is being executed, it may also be caused by abnormal conditions such as communication errors, network failures, or hardware failures during the transaction process. For some reason, its service cannot be performed normally

Once this happens, for a transaction that needs to execute different services of multiple host systems, such as remote cash withdrawal business, it will cause inconsistencies in accounts between bank host systems

[0006] For various data inconsistencies in the online transaction processing system, the existing solution is to manually adjust the inconsistent accounts at the end of the day. The basic idea of ​​this method is When the data inconsistency problem occurs, it can be remedied through an additional intervention process after the event. However, this method may lead to a longer period of data inconsistency, so that the system will call the wrong data when processing other transactions. It leads to a series of data processing errors, which have an impact on the entire trading system due to the inability to control the time when the risk exists

In addition, the method of manually adjusting accounts is labor-intensive, time-consuming, and inefficient
