摘要
针对面向路网和铁路运输作业全过程的大型复杂模拟系统 ,分析了系统中基础数据的特点、应用需求和数据来源 ,以通用性为出发点 ,设计了数据采集、存贮和表示 3层的层次型基础数据管理模型 ,应用Oracle数据库在UNIX平台上 ,采用C语言、VisualC + +语言进行开发 ,实现了二维界面的宏观层和微观层数据录入、编辑和显示。
Regarding the large complicated simulation system for railway net and for the whole process of railway transportation,this paper analyzes the characters,application requirements and sources of the basic data of this system.Taking the compatibility as starting point,it designs three levels of gradational data management models for data acquisition,storage and display.With Oracle's database in Unix platform,developed in C and Visual C++ language,it realizes the data input,edit and display from both macro level and micro level of two\|dimension interface.
