Embodiment Construction

[0033] Without loss of generality, the system parties involved in information synchronization are simplified into the following form: one information service center and three information clients. The general form of network-based connection between the information service center, that is, the server, and the client is as follows: figure 1 shown. The specific network connection method is not considered here, as long as the server and the client can communicate in a certain way.

[0034] The basic information is the data that needs to be used during the execution of data synchronization. The environment refers to the environment in which operations on data and interactions between systems can be performed.

[0035] Taking the synchronous data stored in the information service center as a whole, divide it. It can be a full division or a partial division of the synchronization data, which is set according to specific information synchronization requirements. An example of divi...

Abstract

The invention relates to an asynchronous data synchronization method for distributed systems, comprising an information service center and a plurality of clients. The information service center stores synchronization data, and is provided with a synchronization information table. When the data in the information service center changes, a data update message is transmitted to a target in the synchronization information table. The clients update the synchronization data thereof when receiving the data update message. After data updating, the clients notify the information service center of the latest data version. The information service center updates the synchronization information table after receiving the notice. According to the invention, a data synchronization method characterized in that a synchronous end makes a response asynchronously after one end initiates synchronization is adopted, waste of network resources caused by the existing polling synchronization method is avoided, and the amount of system resources needed for data synchronization is reduced. Moreover, the network communication mode of asynchronous data synchronization is more flexible and adaptive, occupation of the communication network is less, and the data integrity and unity of distributed systems are ensured.

Description

technical field [0001] The invention relates to a computer distributed software system, in particular to a method for synchronizing information in a distributed system. Background technique [0002] In computer software systems, especially distributed systems, there are situations where information needs to be synchronized between multiple systems. Commonly used information synchronization methods include polling and notification. Synchronization by polling is a waste of resources. Because the query needs to be repeated at certain intervals, the cost of polling is determined by the polling interval. Notification is an asynchronous method, and the system in which information changes occurs notifies all systems that need to be synchronized that the information has changed. It is up to the system receiving the notification to decide how to synchronize the information. Contents of the invention [0003] The technical problem to be solved by the present invention is to prov...
