AI Technical Summary

Problems solved by technology

Although the logic of the existing method is simple, since the synchronization process may involve a large amount of data transmission, it seriously occupies transmission resources (for example, network bandwidth), and errors are also prone to occur during data transmission, resulting in data synchronization failure.

Embodiment Construction

[0046] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures.

[0047] The term "comprises", "comprises" or any other variation thereof is intended to cover a non-exclusive inclusion such that a process, method, article or apparatus comprising a set of elements includes not only those elements but also other elements not expressly listed elements, or also elements inherent in such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article or apparatus comprising said element.

Abstract

The invention relates to the technical field of data processing, and provides a data synchronization method and device, a storage medium and electronic equipment. The data synchronization method comprises the following steps: respectively obtaining a synchronization calculation table of a source system and a synchronization calculation table of a target system; searching a first synchronization position from a synchronization calculation table of the source system; and if the first synchronization position is successfully searched, synchronizing the data of the data table of the source system at the first synchronization position and after the first synchronization position into the data table of the target system. According to the method, the amount of data required by full-amount synchronization is remarkably reduced, so that transmission resources are saved, and the possibility of data errors in the transmission process is reduced.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data synchronization method and device, a storage medium and electronic equipment. Background technique [0002] Modern software projects often include multiple business systems of multiple companies. Some data between systems needs to be shared, and cannot be shared due to factors such as system security (sharing means that the same data is used by multiple different systems at the same time), but only Store one copy on each system, and try to ensure that the data stored on each system is consistent. [0003] At present, the method to ensure data consistency is data synchronization, that is, data is copied from the source system to the target system indiscriminately. According to the data synchronization method, data synchronization can be divided into full synchronization and incremental synchronization. The so-called full amount of synchronization, the pract...
