Electronic data synchronization method and electronic data synchronization processing system

The invention relates to the field of electronic information transmission technology of a database, in particular to an electronic data synchronization method and an electronic data synchronization processing system.

At present, the development of commercial application software has expanded and expanded from the internal electronic information transmission and sharing of enterprises with the development and expansion of information network construction such as regional network (LAN), wide area network (WAN) or Internet (Internet). The transfer and sharing of e-commerce information between the business (B2B) or the business to the customer (B2C) enables different hosts on each node of the information network to share relevant information. Take various departments within the company as an example. In order to meet the operational and commercial needs of enterprises, different departments such as production control (planning, manufacturing), logistics management (distribution, procurement, inventory management) and financial management (accounting, finance) Management) Use different host systems, have separate operating systems and their own application systems, then share data through internal or external information networks, and operate together to form a decentralized processing system. The traditional decentralized processing system is that after the user first sends the information to the server, the server then sends the queried data back to the user, so that the data processing efficiency is not high. In particular, when different applications or programs built by enterprises in different periods or across countries are operated in a decentralized processing system, if there is any change in the information shared between different application systems, it needs to be synchronized. For example, at present, a data issuer (such as an application server with or connected to a master repository) should perform data synchronization updates in a multi-data receiver (such as multiple application client) architectures. Way to proceed:

(1) Periodic summary method: After each interval, the issuing end periodically collects the data and sends it to the receiving end by using the register and the timer, but the receiving end does not change the received data. Rong.

(2) Timing synchronization method: Each receiving end uses a one-cycle polling timer to query or visit the sending end for data change after each preset interval time; when it asks that the data of the sending end has some changes, the transmitting end The changed information is sent to each receiving end to update the content with the received data.

(3) Instant synchronization method: When there is a partial change in the data of the originating end, all receiving ends are notified immediately, and only the changed data is transmitted to the corresponding receiving end for change processing.

The above-mentioned periodic summarization method occupies a large amount of system resources and storage space at the originating end and its receiving end, and cannot ensure the instantaneous synchronization of data between the originating end and its receiving end. In addition, in the above-mentioned timing synchronization method, after each pre-set interval expires, each receiving end sequentially visits the data sending end to have data changes, which will make the number of frequent visits and the sending end need to respond one by one, resulting in issuing The data processing at the end is inefficient, and it is also impossible to ensure that the data between the sender and its receiver is instantaneously synchronized. In contrast, although the above-mentioned instant synchronization method can ensure the instant synchronization update of the data, the data issuing end needs to bear the authority to directly manage the data receiving state of the plurality of data receiving ends, and manage the synchronization failure of each data receiving end. Exception handling, and sequential analysis or comparison of each data update task (including new and old data changes), so that the data receiving end of the system resources, if the data synchronization frequency is too high, it will affect the data The data processing speed of the end.
