网络列车运行图分布式数据库访问设计

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

摘要: 对计算机编制列车运行图系统采用C/S结构的分布式数据库技术来组织和管理数据中的关键技术 ———多用户数据访问技术进行了研究,提出了以PowerBuilder和Visual C++为工具,采用ODBC技术来实现系统多用户对数据库的实时访问的方法。实际开发与应用表明,该方法能方便、快速地连接和访问目标数据库。

Abstract: 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.
