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 with

Embodiment Construction

[0045] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] Referring to Fig. 1, it is a flowchart of a method for maintaining data consistency in online data interaction of the present invention, including the following steps:

[0047] Step 101, submitting a data interaction request through the client, triggering the interaction platform to generate a unique corresponding interaction sequence number and notifying the server;

[0048] Step 102, the server completes the data processing and returns a result, and the interaction platform synchronously records the interaction process information to the first information table;

[0049] Step 103, if the data interaction fails, initiate a rollback operation request, the interaction platform records the rollback operation information in th...

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...
