轮式拖拉机CAD系统支撑软件一体化的研究

Research on Integration of Support Softwares for the Wheel Tractor CAD Sysem

结合Mic(?)o-VAX-Ⅱ微型机上的DDM图形系统和RDB数据库管理系统,讨论了轮式拖拉机CAD系统一体化的关键技术,并着重讨论了实现高级语言与数据库、高级语言与图形系统以及数据库与图形系统这三个界面的技术措施。

This paper has studied the-key method about integerity of the Wheel Tractor's CAD System, and the technology method of passing data, through between the high-level Language and Graphic system, Database ahd Graphic System, the high-level Language and-'Database upon DDM Graphic System and RDB Database Manegement System based on Micro-VAX-Ⅱ at detail.
