Abstract: A method of intelligence upgrade was suggested because of the huge works of MIS upgrade, unstable upgrade process and unsafe upgrade files. This upgrading system consisted of Database server, user terminals, uploading terminal and intercepting terminal. The flies of upgrade were put into the Database of MIS. The introducing program in user terminals was in charge of MISt, pgrade. The intercepting terminal was used for help if it was not connected to Database server. The intercepting terminal was responsible for writing the updated connecting information of the Database server. The uploading terminal managed the upgrading file in Database server. This kind of method of upgrade could resolve these questions, e.g., changes of the address of upgrading files, username and passwords of Database. Jincheng Cooperation had successfully used this method of intelligence upgrade, and saved a lot of costs for upgrading and maintaining ERP.
