Embodiment Construction

[0048] 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.

[0049]At present, the solution to realize data synchronization through program coding is generally a special coding process for a specific problem, and the code is only suitable for solving a single problem, and cannot be extended and reused, that is, it is difficult to transplant and reuse. It can be seen that the existing data synchronization scheme through program coding needs to realize data synchronization according to different business scenarios, which does not have wide applicability.

[0050] In addition, when the data of the data receiver is illegally tampered with, the existing data synchronization technology lacks a feedback and correction scheme, that is, it cannot prevent the illegal tampering of the data receiver, an...

Abstract

The embodiment of the invention provides an inter-system data synchronization method and apparatus, and relates to the technical field of data processing. The method comprises the following steps: storing a control instruction corresponding to a local system to form a cloud control instruction, wherein the control instruction comprises an instruction generated by a cloud system for a received service request; comparing a local control instruction periodically transmitted back by the local system with the cloud control instruction, wherein the local control instruction is a control instruction which is released by the cloud system according to the service request and is stored in the local system; and when the transmitted back local control instruction is inconsistent with the cloud control instruction, sending the cloud control instruction to the local system to trigger the local system to correct the transmitted back local control instruction. By adoption of the inter-system data synchronization method and apparatus provided by the embodiment of the invention, the consistency of data of the cloud control instruction and the local control instruction can be guaranteed, and local illegal tampering can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method for synchronizing data between systems and a device for synchronizing data between systems. Background technique [0002] With the rapid development of computer network technology, especially with the increase of data itself and equipment, the demand for data synchronization is becoming more and more intense. [0003] There are usually two processing methods for data synchronization between systems: one is to realize data synchronization through program coding; the other is to directly act on the database to realize data synchronization at the database level. Among them, the implementation of data synchronization at the database level is usually due to problems such as inconsistent table structures between the two parties, limited direct network access between the two parties, or / and synchronization based on complex business conditions, etc., resulting in limited...
