Data synchronization method based on multiple distributed intelligent agents

Abstract

The invention discloses a data synchronization method based on multiple distributed intelligent agents. A distributed system structure of the multiple intelligent agents is adopted; the intelligent agents are deployed in each client side of an information system; the intelligent agents are responsible for storing a view currently displayed at the client side, perceiving and precisely pushing data changes; the intelligent agents in the client side share state information through a public table in an information system database; and views of multiple client sides are refreshed according to requirements through cooperation of the intelligent agents distributed in various client sides. According to the data synchronization method disclosed by the invention, data synchronization information can be precisely pushed, so that differential data synchronization requirements of multiple client sides are satisfied; and simultaneously, resource consumption of networks and databases is reduced.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a data synchronization method based on distributed multi-agents. 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 used in in...

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.
