Electronic data synchronization method and electronic data synchronization processing system

Abstract

The invention relates to an electronic data synchronization method and an electronic data synchronization process system, which are applied between a transmitting terminal and at least one receiving terminal. The electronic data synchronization method comprises the following steps: when data change occurs in the transmitting terminal, at least one change data block is generated by one change generation module; a corresponding process thread and an internal memory space can be established or started according to the identification of the at least one receiving terminal and primary key values in the at least one change data block by a data synchronization module; the at least one change data block is stored into a corresponding internal memory space in sequence according to the data synchronization module; according to the corresponding process thread, operation program values in the first piece of the data block and the last piece of the data block stored in the corresponding internal memory space are analyzed; and steps for transmitting the change data block to the at least one receiving terminal are determined.

Description

technical field [0001] The invention relates to the technical field of electronic information transmission of databases, in particular to an electronic data synchronization method and an electronic data synchronization processing system. Background technique [0002] At present, the development of commercial application software, along with the evolution and expansion of information network construction such as local area network (LAN), wide area network (WAN) or Internet (Internet), has expanded from electronic information transmission and sharing within enterprises to inter-enterprise (B2B) Or business-to-customer (B2C) e-commerce information transmission and sharing, so that different hosts on each node of the information network can share relevant data. Taking the various departments within the enterprise as an example, in order to meet the needs of enterprise operation and business, different departments such as production control (planning, manufacturing), logistics ma...

Problems solved by technology

[0006] Periodic summarization will take up a lot of system resources and storage space at the sender and receiver, and cannot guarantee real-time data synchronization between the sender and receiver

In the timing synchronization method, after each preset interval expires, each receiving end visits the data sending end in order to see if there is any data change, so that the number of visits is frequent and the sending end responds to data one by one, resulting in poor data processing efficiency at the sending end , and also cannot guarantee real-time data synchronization between the sender and receiver

In comparison, although the real-time synchronization method can better guarantee the real-time synchronous update of data, the data sending end needs to bear the responsibility of directly managing the data receiving status of the multiple data receiving ends, and manage the status of each data receiving end when synchronization fails. Exception handling, and sequential analysis or comparison of each data update task (including new and old data changes), consumes more system resources at the data receiving end. If the frequency of real-time data synchronization changes is too high, it will affect the data at the data sending end Synchronous processing speed
