Isomerous data synchronous implementation method

Abstract

The invention discloses an isomerous data synchronous implementation method, which comprises the following steps that a released client side regularly calls and collects a dll (Dynamic Link Library) component to scan a self source data base of the client side, extracts new data, then packages the collected data to be a data packet with an XML (Extensive Makeup Language) format according to a format SOAP (Simple Object Access Protocol), and uploads the data packet to a server; and a collected client side regularly calls a download process to download the data packet with the XML format, classifies and queue manages the newly downloaded data packet according to different application requirements after the download is finished, and then calls and converts the dll component to restore and install the data packet in a corresponding queue into corresponding application. The isomerous data synchronous implementation method can realize synchronization of a data structure and data between any two data bases in an internet environment, is completely based on a uniform platform, and provides completely pluggable support for different sub-systems or external systems on the platform.

Description

[0001] technical field [0002] The invention relates to a method for realizing heterogeneous database structure and data synchronization on a unified data release platform, which is characterized in that it is based on Web Services technology and the concept of middleware, and adopts multiple measures to ensure the safety of the data transmission process. Background technique [0003] After the information is generated, it will be used by different subsystems or external systems. Each subsystem or external system stores and uses data in different ways. Therefore, the data conversion work for different subsystems or external systems will take up a lot of time. time and human resources. [0004] All mainstream database products use the publish / subscribe model to realize data synchronization, but they do not provide synchronization functions for heterogeneous database structures. In addition, although the existing heterogeneous database synchronization tools can realize the s...

AI Technical Summary

Problems solved by technology

[0004] Major mainstream database products adopt the publish / subscribe model to realize the data synchronization function, but do not provide the synchronization function of the heterogeneous database structure

In addition, although the existing heterogeneous database synchronization tools can realize the synchronization of the database structure, every time an additional subsystem or external system is added, the tool itself must be modified around the synchronization function. Not only is the workload huge, but the code is maintainable. sex is not guaranteed

Moreover, these synchronization tools have very little consideration for security, and additional ports need to be opened on the computers participating in the synchronization, which limits their application on the Internet.
