Abstract

A computer processing system for implementing data upgrade includes a communication interface device, at least two application servers and a database server for storing data, wherein the communication interface device detects in real-time a connection state of the communication interface device and each of the application servers, and sends data received from external to an application server connected with itself for processing; all the application servers are connected with the database server to process data and store the processed data in the database server, the data upgrade is implemented in batch for the application servers requiring the data upgrade by disconnecting the application servers from the communication interface device and reestablishing the connection of the application servers with the communication interface device after the data upgrade is completed. During the data upgrade, upgrade may be implemented without shut-down of the system. Most importantly, all the servers available in the system always work at the same time and share the burden in switching, thus improving the working efficiency of the whole system.
