Design on the Access to Distributed Database of the Network Train Diagram System

In this paper the key technique—access to database is studied, which based on the C/S structure to organixe and manage the database on train diagram system. The method to fulfills the real time access to database inmulti users, which takes use of the PowerBuilder andVisual C++as developingtools. Application shows that we can link and access to database rapidly and efficiently with the uses of the method.
