通过对列车运行图系统的体系结构进行研究,提出列车运行图编制系统应采用服务器的三层体系结构和基于分布式的数据库体系结构,并结合基于对象——关系模型的ORACLE数据库管理系统,对数据访问方式进行了探讨。
Through the study of train operating system architecture, proposed train operating diagram compilation system should be based on the server three-tier architecture and distributed database architecture, combined with object-relational model ORACLE database management system, Data access methods were discussed.
