Problems solved by technology

However, this method has disadvantages: it is difficult to control the sequence of calling the http interface. For example, if a synchronization needs to be added first and then modified, the http interface cannot do it, resulting in data synchronization failure.
Therefore, the http interface has the problem of poor reliability

Embodiment Construction

[0048] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] A mobile terminal implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, use of suffixes such as 'module', 'part' or 'unit' for denoting elements is only for facilitating description of the present invention and has no specific meaning by itself. Therefore, "module" and "component" may be mixedly used.

[0050] Please see figure 1 , a data synchronization method for data synchronization of multiple sets of system modules, comprising the following steps:

[0051] Step S100, receiving executed data operation information from the first system module. For example, data operation information such as adding, deleting, updating or querying.

[0052] Step S200, storing the data operation information in a message queu...

Abstract

The invention discloses a data synchronization method, device and system, and the method, device and system are used for the data synchronization between a plurality of system modules. The method comprises the steps: receiving the executed data operation information from a first system module; enabling the data operation information to be stored in a message queue; transmitting the data operation information in the message queue to a second system module in an ordered manner, so that the second system module carries out execution. The method has an effect of improving the reliability of data synchronization.

Description

technical field [0001] The present invention relates to the technical field of system synchronization, in particular to a data synchronization method, device and system. Background technique [0002] When the application system is refactored, a new system is usually built, and then the old and new systems are guaranteed to run at the same time, and then the initial grayscale is transitioned to the new system. Since the old and new systems are running at the same time, the data of the two systems will undergo operations of adding, deleting, updating and querying, which will involve the data synchronization of the two systems. [0003] The existing common method: adopt the method of exposing the http interface to the outside, so that the two systems can expose the http interface to each other and provide the other system call. Then when there is data addition, modification, or deletion, the corresponding http interface is called to synchronize the data. However, this approac...
