Data synchronous system and its method

Abstract

A method for synchronizing data includes collecting data from source application according to collection rule including source application subscribed by object application and data information requiring to be collected, finalizing data conversion between source application and object application according to mapping conversion rule then sending collected data to object application.

Description

technical field [0001] The present invention relates to a data synchronization system and its method, in particular to a data synchronization system and its method for data synchronization based on a subscription relationship. Background technique [0002] In the information age, a large amount of information needs to be collected, transmitted and managed, thus putting forward high requirements for the existing information application technology. Among them, the synchronization and sharing of information is particularly important, and an efficient system and method are needed to realize it. [0003] Data synchronization technology has been widely used in various industries, such as communication and network. For example, in the telecommunication network management system, the telecommunication network system becomes more and more complex. When a network element device is connected to a telecom network management system, the network management system needs to retain all or ...

AI Technical Summary

Problems solved by technology

Therefore, it cannot ensure that the amount of synchronized data is minimized

[0012] Second, the real-time arrival of data cannot be guaranteed

Timing synchronization is obviously difficult to achieve real-time synchronization of data. If real-time synchronization is to be achieved, the synchronization operation must be performed every moment. Such a large amount of data transmission is difficult and uneconomical

For the way of using relational database to synchronize, none of the above-mentioned prior art provides technical means to ensure real-time data synchronization

[0013] 3. The integrity of the transaction cannot be guaranteed

Whether it is timing synchronization or using a relational database to synchronize, the acquisition of data may be irregular and out of order. For example, in the synchronization of data generated by an event operation, the event includes multiple Steps, each step is a trigger condition for subsequent steps, when the information corresponding to these steps is synchronized to the target application, the step information data obtained by the target application should be in the same order as the step information data in the synchronization data source, otherwise it will be synchronized to the target application The step information of the application is probably out of order and cannot be executed again

[0014] Fourth, data filtering and screening cannot be realized

Therefore, it may happen that the synchronization is not synchronized, and the data that should not be synchronized is synchronized instead, which is inefficient and the data transmission volume is also large

[0015] 5. Other systems that are interested in changing data cannot be notified in real time

The data in the above-mentioned prior art can only be synchronized to a fixed target application, so once the target application changes, it is difficult to meet the data synchronization requirements
