Research on error feedback mechanism of information system

Information system is a combination of a series of modules and components. During the running of information system, some errors will happen, so how to express errors, locate errors source and fix errors becomes a vital issue in designing, developing, maintaining and integrating of information system. Firstly, the paper proves the weakness of huge information system by probability method, then briefly introduces traditional error feedback mechanism and their shortages, and puts forward four necessary parts of the whole error feedback mechanism: expression, attaining, location and transmitting of errors, based on virtual machine which can supply with an independent-on-application error feedback system.
