A method for accurately pushing multi-client data modification messages

Abstract

The invention discloses a method for accurately pushing multi-client data modification messages. The method adopts a multi-agent centralized system structure, deploys an agent inside each client of the information system, and these agents are responsible for saving the information currently displayed by the client. View, perception and transmission of data changes, the central agent is responsible for the precise push of view synchronization messages, and the on-demand refresh of multi-client views is realized through the cooperation of the agent in the client and the central agent. The method for accurately pushing multi-client data modification messages of the present invention can realize the precise pushing of data synchronization messages to meet the differentiated data synchronization requirements of multiple clients; through the accurate pushing of view synchronization messages, unnecessary message sending is eliminated and synchronization is guaranteed The required clients are synchronized in real time, which not only reduces the occupation of network channel resources, but also eliminates unnecessary database query requests and reduces the consumption of database resources.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method for accurately pushing multi-client data modification messages. Background technique [0002] With the development of computer and network technology, informatization has become a basic means for enterprises to coordinate resources and enhance competitiveness. Various information systems emerged as the times require. In an enterprise intranet, information systems mostly exist in the form of client / server. The information system in the form of "client + database" is the simplest and most common information system. In an information system, multiple clients are often distributed and can access the database to process information. In this way, after one of the clients modifies the shared database, the display views of other online clients must also synchronize the impact of the "modification". At the same time, authority management and multi-view modes are often us...

Problems solved by technology

This method is suitable for the field of equipment monitoring, which reduces the number of times of accessing the database and reduces the consumption of system resources, but uses a complex hierarchical object update method on the client side, which increases the difficulty of client development. At the same time, in this method , the synchronization message will be sent to all clients. After the client receives the synchronization message, it will refresh all the synchronization objects. It does not consider the difference in the client's running status, that is, the view synchronization requirement, resulting in unnecessary data refresh of the client.
