ROSEC++接口在STEP数据交换中的实现研究

The Implementation of ROSE C++ Interfacein STEP Data Exchange

介绍了ROSEC++接口在STEP数据交换中的实现。即利用美国STEPTools公司提供的ROSE工具,对Part21物理文件进行操作和处理生成ROSE数据库,以其为中介,利用ROSEC++接口将船的三维线框模型数据存到SQLSERVER数据库中。重点讨论了ROSE数据库的生成、组织及其应用,以及EXPRESS描述语言到数据库的映射。最后对ROSE和SDAI作了一个比较。

This paper presented the implementation of ROSE C++ interface in STEP data exchange. It uses the ROSE interface tools provided by STEP Tools company to work on the P21 files and convert it to ROSE database. Using it as an agent, we can retrieve the three-dimensional ship wire model data and store them into a database through ROSE C++ interface. This paper focused on the generation, structure and application of ROSE database. It also expounded how to map the EXPRESS description to database. Finally it compared the ROSE and SDAI(Standard Data Access Interface).
