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...

Embodiment Construction

[0036] Such as figure 1 , the heterogeneous data synchronization method of the present invention mainly includes two steps:

[0037] 1) Data Collection Release: The release client regularly invokes the collection dll component to scan the source database of the release client itself, extract new data, and then encapsulate the collected new data into an XML-format data packet according to the required format SOAP and upload it to the server.

[0038] 2) Data Restoration Transition: The collection client regularly invokes the download process to download data packets in XML format. After the download is complete, the newly downloaded data packets are classified and queued according to the needs of different applications, and then the conversion dll component is called to restore and install the data packets in the corresponding queue to the corresponding in the application.

[0039] The present invention will be further described below in conjunction with accompanying drawi...
