Discuss on a Virtual Data on the Web

This paper describes the virtual datapsilas conception and examples and proposes a scheme to integrate these data. Now the information systems grow so fast, this situation lets the communication among systems more complicate. So it will be very difficult to handle the logical business when the old way is used to define the different data and the complex, no- transplantable and humdrum way to handle them. This article summarizes the overall characters of the all complex data, propose a new processing mode ----the flat-form of the virtual data handling. And at last there is an example to show how to do in a factual situation.
