铁路客票系统中调图策略的研究与实现

Study and Implementation of The Scheme in The Process of Updating Data That Concern with Train's Running in The China Railway Ticketing and Reservation System

    摘要
  • 摘要: 调图过程在铁路客票系统中涉及的表多,数据修改量大,通过面向数据的逻辑分析,建立了调图数据模型和逻辑模型,制定了调图策略,提出了主键数据的稳定性应该按照逻辑模型层次递增的观点,并详细论述了客票系统中调图策略的实现.
