部级客调临客命令子系统程序设计

Ministerial Level Dispatching Management Program of Commanding Sub system of Extra Passenger Trains

临客主要集中在节假日开行。通过部级客调计算机管理子系统，可以达到数据共享、准确，信息集中，方便查询、统计，提高工作效率。数据库内容要求简洁，功能齐全，便于使用和维护，并与其他功能模块数据共享，编程中的关键问题，如数据录入、车次、开行、停运、修改和转储等进行了说明。

The extra passenger trains are mainly operated in holidays.Through the ministerial dispatching computer management sub system, data can be shared,information is centralized and is convenient for inquiring and statistics,and working efficiency is raised.The data base requires simple content,is fully fundctional and convenient for usage and maintenance,and can share data with other funtional modem.The paper expounded the key issues in programming,such as data key ing,train number,operation,stopping service,revision and storage transit.
